The claimed invention provides a novel compound not having been studied before, that is, a diene carboxylate anion that contains a specific structure, and a salt thereof. The claimed invention further provides a diene carboxylate anion and a salt thereof, especially a metal salt thereof, which are easily soluble in general organic solvents, reactive diluents, and resins, may be in a liquid state at normal temperature depending on the structure, and have high polymerizability. Polymerization/curing of these produces a resin to which many ionic bonds and a metal are introduced, providing various properties such as hardness, scratch resistance, anti-fingerprint property, gas-barrier property, water vapor barrier property, oxygen absorption property, ultraviolet protection, infrared protection, color development and coloring, high refractive index, adhesion, various catalytic abilities, fluorescence ability and light-emitting ability, optical amplification, dispersibility, and antistatic properties. In addition, the anion and the salt can be used for raw materials for functional fine particles and for metal nanoparticle composites, and also for MOD materials. The claimed invention also provides an advantageous method for producing the diene carboxylate anion and the salt thereof.

Diene-based carboxylate anion and salt thereof, and polymerizable or curable composition thereof

An &#x3b1;-(unsaturated alkoxyalkyl)acrylate composition is provided which enables an &#x3b1;-(unsaturated alkoxyalkyl)acrylate product to be stored at a high purity for an extended period of time and can fully suppress problems such as discoloration and gelation from arising during polymerization, and a method of safely preparing &#x3b1;-(unsaturated alkoxyalkyl)acrylate compositions industrially, with high purity. The composition includes an &#x3b1;-(unsaturated alkoxyalkyl)acrylate of a specific structure and an antioxidant, the content of the antioxidant being from 0.03 to 0.5 wt % per 100 wt % of the &#x3b1;-(unsaturated alkoxyalkyl)acrylate.

&#x3b1;-(unsaturated alkoxyalkyl) acrylate composition and process for production thereof

The present invention provides: resins which can be used for various applications such as radical curable resin compositions, colorant-dispersed compositions, and photosensitive resin compositions; resin compositions; and means for producing the resins. Specifically, the present invention provides an &#x3b1;-allyloxymethylacrylic copolymer having in its main chain a structural unit represented by formula (1): wherein R is a hydrogen atom or a C1-C30 organic group.

&#x3b1;-Allyloxymethylacrylic acid-based copolymer, resin compositions, and use thereof

Provided is an alkali-soluble maleimide-based copolymer which comprises, as essential constituents, 5 to 50% by mass of a maleimide monomer unit which is at least one unit selected from the group consisting of a N-cyclohexylmaleimide monomer unit, a N-benzylmaleimide monomer unit and a substituted N-benzylmaleimide monomer unit, 8 to 30% by mass of the (meth)acrylic acid monomer unit and 30 to 87% by mass of a (meth)acrylic acid ester monomer unit and which satisfies the condition represented by the formula:0.4&#xd7;0.5&#xd7;10where X is the content, in % by mass, of the N-cyclohexylmaleimide monomer unit, the N-benzylmaleimide monomer unit and the substituted N-benzylmaleimide monomer unit and Y is the content, in % by mass, of the (meth)acrylic acid monomer unit. Also provided are a color filter and a liquid crystal display which are formed by using the ionizing radiation-curable resin composition.

Alkali-soluble maleimide copolymer and liquid crystal display comprising the same

The present invention provides: a photosensitive resin composition, which can form uniform coating films having higher coating film strength without causing surface contamination, decrease of evenness of coating films, decrease of film thickness, and coloring by decomposition in heat treatment of subsequent steps, and has good sensitivity of exposure. The photosensitive resin composition comprises a lactone-ring-containing polymer (A) as an essential component, wherein: the lactone-ring-containing polymer (A) is obtained by carrying out polymerization of comonomers and lactonization at the same time wherein the comonomers include a 2-(hydroxyalkyl)acrylate ester and an acidic-group-containing monomer; and the lactone-ring-containing polymer (A) is obtained by almost quantitatively carrying out lactonization of a 2-(hydroxyalkyl)acrylate ester structural unit.
