Abstract
Abstract A gel coating resin composition comprises (A) 10 to 45 parts by weight of an unsaturated polyester with an equivalent amount of unsaturated groups ranging from 140 to 330, (B) 15 to 60 parts by weight of a styrene monomer, and (C) 15 to 75 parts by weight of a polyfunctional (meth)acrylic monomer represented by the following general formula (I) and which has an equivalent amount of unsaturated groups ranging from 89 to 130: ##STR1## where at least four of the R's present are (meth)acryloxy groups, with the remainder being an organic group except (meth)acryloxy groups; and n is an integer of 1 to 5.

Dependent Claim
106 words
A gel coating resin composition comprising (A) 10 to 45 parts by weight of an unsaturated polyester with an equivalent weight per unsaturated group ranging from 140 to 330, (B) 15 to 60 parts by weight of a styrene monomer, and (C) 5 to 75 parts by weight of a polyfunctional (meth)acrylic monomer represented by the following general formula (I) and which has an equivalent weight per unsaturated group ranging from 89 to 130: ##STR3## where at least four of the R groups present are (meth)acryloxy groups, with the remainder being an organic group except (meth)acryloxy groups; and n is an integer of 1 to 5.
Claim 3
Dependent Claim
24 words
A resin composition according to claim 1 wherein the equivalent weight per unsaturated group in the unsaturated polyester (A) ranges from 140 to 300.
Claim 4
Dependent Claim
145 words
In a shaped article chiefly made of a thermosetting resin, the improvement wherein said article has one or two gel-coated surface layers formed of a cured resin composition comprising (A) 10 to 45 parts by weight of an unsaturated polyester with an equivalent weight per unsaturated group ranging from 140 to 330, (B) 15 to 60 parts by weight of a styrene monomer, and (C) 15 to 75 parts by weight of a polyfunctional (meth)acrylic monomer represented by the following general formula (I) and which has an equivalent weight per unsaturated group ranging from 89 to 130: ##STR4## (where at least four of the R groups present are (meth)acryloxy groups, with the remainder being an organic group except (meth)acryloxy groups; and n is an integer of 1 to 5), the second surface layer being optionally made of a gel coating of an unsaturated polyester resin.
Claim 5
Dependent Claim
145 words
In a shaped article chiefly made of a thermosetting resin, the improvement wherein said article has one or two gel-coated surface layers formed of a cured resin composition comprising (A) 10 to 45 parts by weight of an unsaturated polyester with an equivalent weight per unsaturated group ranging from 140 to 330, (B) 15 to 60 parts by weight of a styrene monomer, and (C) 15 to 75 parts by weight of a polyfunctional (meth)acrylic monomer represented by the following general formula (I) and which has an equivalent weight per unsaturated group ranging from 89 to 130: ##STR4## (where at least four of the R groups present are (meth)acryloxy groups, with the remainder being an organic group except (meth)acryloxy groups; and n is an integer of 1 to 5), the second surface layer being optionally made of a gel coating of an unsaturated polyester resin.
