A triazine-ring-containing polymer characterized by including a repeating unit structure represented by formula (1). [In the formula, R and R' each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and [in the formulas, Wand Weach independently represent CRR(Rand Reach independently represent a hydrogen atom or a C1-10 alkyl group optionally substituted by a halogen atom (where these together may form a ring)), C&#x2550;O, S, SO, or SO.]]

Triazine-ring-containing polymer and composition including same

For example, a thin film that has a high refractive index and is capable of forming a fine pattern can be obtained by using a triazine-ring-containing polymer that includes a repeating unit structure represented by formula [4]. 

A triazine ring-containing polymer which contains a repeating unit structure represented by, for example, formula [4] has a high refractive index and also has excellent solubility in various organic solvents including low-polarity solvents, hydrophobic solvents and low-boiling point solvents. A thin film having a high refractive index and excellent transparency can be formed using a composition for film formation use which contains the polymer. 

Triazine ring-containing polymer, and composition for film formation use containing same

It is possible to obtain a thin film that can form a minute pattern and that has a high index of refraction by using a polymer containing a triazine ring and containing a repeating unit structure represented for example by formula (22) or (26). 

Polymer containing triazine ring and composition containing same

A film-forming composition for ink-jet coating which comprises: a triazine-ring-containing polymer including, for example, the repeating unit structure represented by the following formula [3]; and an organic solvent comprising more than 50 mass % solvent based on a glycol dialkyl ether. The composition is less apt to corrode the heads of ink-jet coating devices, and droplets thereof are satisfactorily ejected in ink-jet coating. Therefore, with the composition, it is possible to easily produce a high-refractive-index film according to a desired pattern through pattern printing by an ink-jet coating device. 

Film-forming composition for ink-jet coating

A solvent-free light-curable adhesive composition includes: for example, a triazine ring-containing polymer including a repeating unit structure represented by formula [3] and having a weight-average molecular weight of 500-5000; and a reactive diluent such as N-vinylformamide, the composition not including a solvent. The solvent-free light-curable adhesive composition has good compatibility with acrylic materials and the like, which are adhesive components, even without including a solvent. 

Solvent-free light-curable adhesive composition

A composition comprising both a polymer which contains triazine-ring-containing repeating units represented by formula (17) and a crosslinking agent which consists of either a poly-functional epoxy compound or a polyfunctional (meth)acrylic compound can be photo-cured even without the addition of an initiator to yield a cured film having a high refractive index and high heat resistance. Thus, a photocurable film-forming composition that comprises a triazine-ring-containing polymer, which can achieve, even without the addition of a metal oxide by the polymer alone, high heat resistance, high transparency, a high refractive index, high solubility and low volume shrinkage, and that is curable even without the addition of an acid generator can be provided. 

Photocurable film-forming composition and manufacturing method for cured film

Provided is a composition for forming a protective film for a transparent conductive film, said composition comprising a triazine ring-containing hyperbranched polymer comprising a repeating unit structure represented by formula (1) and a crosslinking agent having a molecular weight of 1,000 or greater. In formula (1): R and R' independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group or an aralkyl group; and Ar represents a definite aromatic ring-containing group.

Composition for forming protective film for transparent conductive film

For example, a thin film which has a high refractive index and which it is possible to form a fine pattern can be obtained by using a composition that contains a triazine-ring-containing polymer that includes a repeating unit structure represented by formula [5]. 

Triazine-ring-containing polymer and composition containing same

Provided is a triazine ring-containing hyperbranched polymer comprising the repeating unit structure represented by formula (1) and having one or more triazine ring terminals, said one or more triazine ring terminals being capped with a compound that differs from the diamine compound serving as the starting material for the polymer and has at least two active hydrogen groups. In addition to the polymer itself exhibiting high heat resistance, high transparency, a high refractive index, high light resistance, high solubility, and low volume shrinkage, it is also possible to use the polymer to provide a composition for film formation capable of yielding a thick film having high hardness. (In formula (1), R and R' each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and Ar represents a divalent organic group containing an aromatic ring and/or a heterocyclic ring.)

With a photocurable composition for film formation which comprises a polymer containing a repeating unit structure having a triazine ring, for example, one represented by the following formula (17), a crosslinking agent, an ultraviolet absorber, and a light stabilizer, it is possible to produce a cured film which has a high refractive index and satisfactory weatherability 

Composition for film formation

A film-forming composition that contains a tricarbonyl-benzene hyperbranched-polymer cross-linker and a triazine-containing hyperbranch, as shown for example in the formula, can form a thin film that excels in terms of hardness and heat tolerance and exhibits a reduced decrease in index of refraction despite the addition of the cross-linker.

Disclosed is a triazine ring-containing hyperbranched polymer containing a repeating unit structure represented by the expression (1). By this means, it is possible to achieve a triazine ring-containing polymer which, alone, has high heat resistance, high transparency, high refractive index, high light resistance, high solubility, low volume shrinkage without adding metal oxides; and also a membrane-forming composition containing the same. In the formula, R and R' represent independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and A represents an alkylene group optionally having a branched or alicyclic structure of 1 to 20 carbon atoms.

Furthermore, this film-forming composition, which includes the same polymer, crosslinking agent and fine inorganic particles having a cross-linkable functional group, is able to provide cured films with good high temperature and high humidity resistance. 

A film-forming composition including a triazine ring-containing hyperbranched polymer with a repeating unit structure indicated by formula (1), and inorganic micro particles is provided. This enables the provision of a film-forming composition capable of hybridizing without reducing dispersion of the inorganic micro particles in a dispersion fluid, capable of depositing a coating film with a high refractive index, and suitable for electronic device film formation. In the formula, R and R' are mutually independent and indicate a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and Ar indicates a divalent organic group including either an aromatic ring or a heterocyclic ring, or both.
