Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
66 words
A radiation curable, water-miscible resin composition comprising (1) a nonionic water-miscible diacrylate of a diglycidyl ether of an aliphatic diol, said diol being a lower molecular weight alkanediol or a polyalkylene glycol, said glycol having a molecular weight of less than 1,000, said diacrylate containing no free carboxyl groups or salts thereof and (2) water in an amount to significantly reduce the viscosity of said composition.
Claim 2
Dependent Claim
66 words
A radiation curable, water-miscible resin composition comprising (1) a nonionic water-miscible diacrylate of a diglycidyl ether of an aliphatic diol, said diol being a lower molecular weight alkanediol or a polyalkylene glycol, said glycol having a molecular weight of less than 1,000, said diacrylate containing no free carboxyl groups or salts thereof and (2) water in an amount to significantly reduce the viscosity of said composition.
Claim 3
Dependent Claim
13 words
The resin composition of claim 1 wherein said polyalkylene glycol is polyethylene glycol.
Claim 4
Dependent Claim
13 words
The resin composition of claim 1 wherein said polyalkylene glycol is polypropylene glycol.
Claim 5
Dependent Claim
11 words
The resin composition of claim 1 including a water-miscible reactive diluent.
Claim 6
Dependent Claim
14 words
The resin composition of claim 4 wherein said reactive diluent is a hydroxyalkyl acrylate.
Claim 7
Dependent Claim
13 words
