Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 87 words
A radiation curable composition prepared by the process of reacting 1 mole of a polyepoxide having n epoxide groups per molecule, wherein n has a value of 2-4, with about n-1 moles of acrylic acid or methacrylic acid, followed by reacting the resulting product with about 0.5 to 1 mole of phosphoric when n is 2 and 1 mole of phosphoric acid when n is 3 or 4 in the presence of at least about 1.0 equivalent of a hydroxyl group-containing material per mole of phosphoric acid.
Claim 2
Dependent Claim 87 words
A radiation curable composition prepared by the process of reacting 1 mole of a polyepoxide having n epoxide groups per molecule, wherein n has a value of 2-4, with about n-1 moles of acrylic acid or methacrylic acid, followed by reacting the resulting product with about 0.5 to 1 mole of phosphoric when n is 2 and 1 mole of phosphoric acid when n is 3 or 4 in the presence of at least about 1.0 equivalent of a hydroxyl group-containing material per mole of phosphoric acid.
Claim 3
Dependent Claim 11 words
The composition of claim 1 wherein the acid is acrylic acid.
Claim 4
Dependent Claim 11 words
The composition of claim 1 wherein the acid is methacrylic acid.

Claim 9
Dependent Claim 65 words
A radiation curable composition prepared by the process of reacting about 1 mole of a polyepoxide having about 2 epoxide groups per molecule with about 1 mole of acrylic acid, followed by reaction of the resulting product with about 1 mole to about 0.5 mole of phosphoric acid in the presence of at least about 1.0 equivalent of hydroxyl group per mole of phosphoric acid.
Claim 10
Dependent Claim 65 words
A radiation curable composition prepared by the process of reacting about 1 mole of a polyepoxide having about 2 epoxide groups per molecule with about 1 mole of acrylic acid, followed by reaction of the resulting product with about 1 mole to about 0.5 mole of phosphoric acid in the presence of at least about 1.0 equivalent of hydroxyl group per mole of phosphoric acid.
Claim 11
Dependent Claim 103 words
A process for preparing an ultraviolet curable monomer which produces good adhesion to metal in cured state coatings, which comprises reacting about 1 mole of a polyepoxide having n epoxide groups per molecule wherein n has a value of about 2 to about 4 with about n-1 moles of acrylic acid, followed by reaction of the resulting product with about 0.5 to about 1 mole of phosphoric acid when n is 2 and 1 mole of phosphoric acid when n is 3 or 4 in the presence of at least about 1 equivalent of a hydroxyl group-containing material per mole of phosphoric acid.
Claim 12
Dependent Claim 103 words
A process for preparing an ultraviolet curable monomer which produces good adhesion to metal in cured state coatings, which comprises reacting about 1 mole of a polyepoxide having n epoxide groups per molecule wherein n has a value of about 2 to about 4 with about n-1 moles of acrylic acid, followed by reaction of the resulting product with about 0.5 to about 1 mole of phosphoric acid when n is 2 and 1 mole of phosphoric acid when n is 3 or 4 in the presence of at least about 1 equivalent of a hydroxyl group-containing material per mole of phosphoric acid.
Claim 13
Dependent Claim 16 words
