There is provided a curable resin composition that exhibits high adhesive properties to materials such as glass, copper, aluminum, PET, and PC, which have been regarded as poor adherends relative to photo-curable compositions, and high adhesive properties also between adherends different from each other. A curable resin composition including a polyene compound of Formula (1): (where n1, n2, and n3 are each independently an integer of 2 to 4; and Rto Rare each independently a hydrogen atom or a Calkyl group). The composition may further include a thiol compound or a photopolymerization initiator. The thiol compound may be a compound having two to six thiol groups in the molecule, or be an aliphatic thiol, or be produced by a reaction of an aliphatic mercapto carboxylic acid and a polyhydric alcohol. The polyhydric alcohol may be an aliphatic polyhydric alcohol or hydroxyalkyl isocyanurate.

Photo-curable resin composition

It is an object to provide a liquid thermosetting composition that yields an epoxy resin having physical properties of the cured product such as high flexural strength along with adequate handleability as liquid, to be used in transparent sealants for optical semiconductors, such as transparent sealants for LEDs (light-emitting devices) and the like. There is provided a thermosetting composition containing an epoxy compound that a side chain between a triazinetrione ring and an epoxy group substituted on the triazinetrione ring is long (elongated).

Long chain alkylene group-containing epoxy compound

A curable composition that maintains good handleability in the liquid form and that can be photo- or heat-cured to form a cured product having physical properties including both high transparency and high flexural strength. A curable composition includes, an epoxy compound of (1): [where each of E, E, and Eis independently an organic group of Formula (2) or Formula (3); and each of R, R, and Ris independently an optionally branched alkylene group or oxyalkylene group: (where Ris a hydrogen atom or a methyl group)]; and an acid generator.

Long-chain alkylene-containing curable epoxy resin composition

There is provided a resist composition suitable for forming a microlens which is excellent in transparency, heat resistance, and sensitivity characteristics, excellent in solubility in a developer, and as the result thereof has high resolution. A positive resist composition comprising; a component (A): an alkali-soluble polymer; a component (B): a compound having an organic group to be photolyzed to generate an alkali-soluble group; a component (C): a crosslinkable compound of Formula (1): [where R, R, and, Rare independently a Calkylene group or oxyalkylene group which are optionally branched; and E, E, and Eare independently a group containing a structure of Formula (2) or Formula (3): (where Ris a hydrogen atom or a methyl group)]; and a component (D): a solvent.

Positive resist composition and method for producing microlens

Resin composition for powder coating

A process for producing a silver coated copper powder, characterized in that a metal silver is precipitated on the surface of a metal copper powder by means of a silver complex solution comprising a silver salt, an ammonium carbonate compound and ammonia water as essential components.
