The present invention provides an isocyanate prepolymer prepared by reacting an organic di-isocyanate with an unsaturated alcohol dimer having 16 to 24 carbon atoms and/or a hydrogen addition product of the unsaturated alcohol dimer and a process for preparing the same.

Isocyanate prepolymer and process for preparing the same

A polyvinyl chloride resin composition is disclosed, which comprises (a) a vinyl chloride homo- or copolymer, (B) a plasticizer, (C) a blocked urethane prepolymer as essential components, the blocked urethane prepolymer (C) being a prepolymer of isocyanurate type polyisocyanate prepared from an alkylene diisocyanate which may contain in the alkylene chain thereof a substituted or unsubstituted cyclohexane or aromatic ring.

Polyvinyl chloride resin composition

An activation energy-curable resin composition comprising as an essential ingredient a resin obtained by reacting (a) a reaction product of a novolak-epoxy compound and an unsaturated monocarboxylic acid, (b) a reaction product of a diisocyanate and a poly(meth)acrylate having a hydroxyl group per moleucle and (c) at least one of an aromatic, aliphatic or alicyclic polybasic acid (or an anhydride thereof).

Composition comprising vinyl ester, unsaturated urethane and polybasic

An activation energy-curable resin composition comprising as an essential ingredient a resin obtained by reacting (a) the reaction product of a novolac epoxy compound and an unsaturated monocarboxylic acid with (b) the reaction product of a diisocyanate and a poly(meth)acrylate having one hydroxyl group for each molecule.

Activation energy-curable resin composition

A powder coating resin composition comprising (A) a phosphorus-containing vinyl polymer containing a curable functional group and having a softening point, determined by the ring and ball method, of 70.degree. to 150.degree. C. and a number average molecular weight of 1500 to 30000, and (B) a curing agent.

Powder coating resin composition

A resin composition for powder paints, said composition comprising (I) 70 to 97% by weight of a polyester resin containing free carboxyl groups in the molecule and having an acid value of 20 to 100 KOH mg/g and a softening point of 70.degree. to 150.degree. C and (II) 3 to 30% by weight of glycidyl p-glycidyloxybenzoate.
