Abstract
Abstract Curable coating compositions particularly suitable as a vehicle for printing inks, comprising a resin obtained by esterifying with acrylic or methacrylic acid a hydroxyl group-containing resin prepared either by reacting ingredients (A) and (B) to form a reaction mixture which is then reacted with ingredient (C) or by reacting the ingredients (A), (B) and (C). The ingredient (A) is a five-membered cyclic compound having conjugated double bonds or a Diels-Alder's reaction product thereof, the ingredient (B) a compound having both a polymerizable double bond and a hydroxyl group in the molecule and (C) a resol type phenolic resin.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
137 words
A curable coating composition comprising a resin obtained by reacting the following ingredients (A), (B) and (C) (a) at least one member selected from the group consisting of (1) five-membered cyclic compounds having unsaturated conjugated double bonds, represented by the following general formula ##STR2## wherein R is an organic residue having 1 - 3 carbon atoms, and m and n are each an integer with the proviso that the sum thereof is 6 and (2) Diels-Alder's products of the five-membered cyclic compounds (1) (B) at least one compound containing both a polymerizable double bond and a hydroxyl group in the molecule, and (C) at least one resol type phenolic resin, to produce a hydroxyl group-containing resin, and then reacting the thus-produced hydroxyl group-containing resin with a member selected from the group consisting of acrylic and methacrylic acids.
Claim 2
Dependent Claim
137 words
A curable coating composition comprising a resin obtained by reacting the following ingredients (A), (B) and (C) (a) at least one member selected from the group consisting of (1) five-membered cyclic compounds having unsaturated conjugated double bonds, represented by the following general formula ##STR2## wherein R is an organic residue having 1 - 3 carbon atoms, and m and n are each an integer with the proviso that the sum thereof is 6 and (2) Diels-Alder's products of the five-membered cyclic compounds (1) (B) at least one compound containing both a polymerizable double bond and a hydroxyl group in the molecule, and (C) at least one resol type phenolic resin, to produce a hydroxyl group-containing resin, and then reacting the thus-produced hydroxyl group-containing resin with a member selected from the group consisting of acrylic and methacrylic acids.
Claim 3
Dependent Claim
32 words
A curable coating composition according to claim 1, wherein the ingredients (A) and (B) are reacted with each other to form a reaction mixture which is then reacted with the ingredient (C).
Claim 4
Dependent Claim
21 words
A curable coating composition according to claim 1, wherein the ingredients (A), (B) and (C) are reacted together at a time.
