Abstract
Abstract An alcoholic varnish comprising an alcoholic solution of a hydroxyl group-containing copolymer resin of cyclopentadiene, dicyclopentadiene or an alkyl-substituted derivative thereof and a compound, such as allyl alcohol, having at least one double bond and at least one hydroxyl group in the molecule. In one embodiment, this invention relates to an alcoholic varnish comprising an alcoholic solution of said hydroxyl group-containing resin and at least one known alcohol soluble resin such as maleinated rosin or alkyd resin.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
An alcoholic varnish comprising a solution in an alcohol of a resin containing hydroxyl groups, prepared by reacting (A) at least one compound selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted derivatives thereof with (B) a compound having at least one double bond and at least one hydroxyl group in the molecule in the presence of at least one other polymerizable compound in an amount not exceeding the amount of the compound (A) used, said at least one other polymerizable compound being selected from the group consisting of styrene, indene, vinyl acetate and phenolic compounds.
Claim 2
Dependent Claim
97 words
An alcoholic varnish comprising a solution in an alcohol of a resin containing hydroxyl groups, prepared by reacting (A) at least one compound selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted derivatives thereof with (B) a compound having at least one double bond and at least one hydroxyl group in the molecule in the presence of at least one other polymerizable compound in an amount not exceeding the amount of the compound (A) used, said at least one other polymerizable compound being selected from the group consisting of styrene, indene, vinyl acetate and phenolic compounds.
Claim 3
Dependent Claim
72 words
An alcoholic varnish comprising a solution in an alcohol of a resin containing hydroxyl groups, prepared by reacting (A) at least one compound selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted derivatives thereof with (B) a compound having at least one double bond and at least one hydroxyl group in the molecule, said hydroxyl group-containing resin being prepared by reacting with a resol type phenol resin at an elevated temperature.
Claim 4
Dependent Claim
72 words
An alcoholic varnish comprising a solution in an alcohol of a resin containing hydroxyl groups, prepared by reacting (A) at least one compound selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted derivatives thereof with (B) a compound having at least one double bond and at least one hydroxyl group in the molecule, said hydroxyl group-containing resin being prepared by reacting with a resol type phenol resin at an elevated temperature.
Claim 5
Dependent Claim
89 words
An alcoholic varnish comprising a solution in an alcohol of a resin containing hydroxyl groups, prepared by reacting (A) at least one compound selected from the group consisting of cyclopentadiene, dicyclopentadiene and alkyl-substituted derivatives thereof with (B) a compound having at least one double bond at least one hydroxyl group in the molecule, said hydroxyl group-containing resin being prepared by mixing or reacting with at least one alcohol soluble resin selected from the group consisting of maleinated rosin, shellac, phenolic resins, polyamide resins, alkyd resins and modified petroleum resins.
Claim 6
Dependent Claim
89 words
