Abstract
An adhesive resin composition comprising a polymer of a radically polymerizable epoxy resin (I) and a monomer (c), the radically polymerizable epoxy resin (I) being a reaction product between an epoxy resin (a) and a radically polymerizable monomer (b) having a function group reactive to epoxy group or hydroxyl group in said epoxy resin (a), having an equivalent ratio (b)/(a)=0.01.about.0.9 and said monomer (c) being copolymerizable with said radically polymerizable epoxy resin (I) and containing alkyl (meth)acrylate and/or a fluorine-containing unsaturated monomer serving as an indispensable component. The adhesive resin composition has an excellent adhesion between fluorine-contained resins and metal substrates.

A method of adhering a fluorine-containing resin to a metal substrate comprising:
- applying between a fluorine-containing resin and a metal substrate, an adhering effective amount of an adhesive composition consisting essentially of a polymer of a radically polymerizable epoxy resin (I) and a monomer (c),
- said radically polymerizable epoxy resin (I) being a reaction product between an epoxy resin (a) and a radically polymerizable monomer (b) having a functional group reactive to an epoxy group or a hydroxyl group in said epoxy resin (a) selected from the group consisting of carboxyl groups, hydroxyl groups and a mixture thereof,
- having an equivalent ratio (b')/(a')=0.01-0.9, wherein (b') represents an equivalent of said functional group of said radially polymerizable monomer (b) which reacted with said epoxy resin (a) and (a') represents an equivalent of said epoxy group or hydroxyl group in said epoxy resin (a), and
- said monomer (c) being copolymerizable with said radically polymerizable epoxy resin (I) and containing alkyl(meth)acrylate, fluorine-containing unsaturated monomer, or mixture thereof, serving as an indispensable component.
A laminate comprising:
- i) a fluorine-containing resin;
- ii) a metal substrate;
- iii) an adhesive composition, wherein said adhesive composition is disposed between said fluorine-containing resin and said metal substrate;
- and
- wherein said adhesive composition consists essentially of a polymer of a radically polymerizable epoxy resin (I) and a monomer (c),
- said radically polymerizable epoxy resin (I) being a reaction product between an epoxy resin (a) and a radically polymerizable monomer (b) having a functional group reactive to an epoxy group or a hydroxyl group in said epoxy resin (a) selected from the group consisting of carboxyl groups, hydroxyl groups and a mixture thereof,
- having an equivalent ratio (b')/(a')=0.01-0.9, wherein (b') represents an equivalent of said functional group of said radically polymerizable monomer (b) which reacted with said epoxy resin (a) and (a') represents an equivalent of said epoxy group or hydroxyl group in said epoxy resin (a), and
- said monomer (c) being copolymerizable with said radically polymerizable epoxy resin (I) and containing alkyl(meth)acrylate, fluorine-containing unsaturated monomer, or mixture thereof, serving as an indispensable component.
