Abstract
Actinic radiation curable compositions comprising at least one actinic radiation curable, cationically polymerisable compound and at least one cationic photoinitiator, may be stabilised by the use of a stabiliser which is a complex of a Lewis acid (other than a fluorine-containing boron compound) and a Lewis base.

1-24. (canceled)
An actinic radiation curable composition comprising:
- (A) at least one actinic radiation curable cationically polymerisable compound;
- (B) at least one cationic photoinitiator;
- and
- (C) at least one stabilizer which is a complex of a Lewis acid and a Lewis base, provided that the Lewis acid is not a fluorine-containing boron compound and wherein the stabilizer is present in the actinic radiation curable composition in an amount of between 0.001 weight % to 0.3 weight %.
An actinic radiation curable composition comprising:
- (A) 40-80 weight % of at least one liquid epoxy resin having an epoxy functionality of 2 or greater;
- (B) 0.1 -10 weight % of at least one cationic photoinitiator;
- (C) 5-40 weight % of at least one liquid diacrylate;
- (D) 0-15 weight % of at least one liquid poly(meth) acrylate having a (meth)acrylate functionality of greater than 2;
- (E) 0.1 -15 weight % of at least one radical photoiniator;
- (F) 5-40 weight % of at least one OH-terminated polyether, OH-terminated polyester or OH-terminated polyurethane;
- and
- (G) 0.001-0.3 weight % of at least one stabilizer which is a complex of a Lewis acid and a Lewis base, provided that the Lewis acid is not a fluorine-containing boron compound.
A stabilizer comprising a complex of a Lewis acid and a Lewis base provided that the Lewis acid is not a fluorine-containing boron compound and wherein the stabilizer stabilizes an actinic radiation curable composition.
A method of producing a cured product comprising treating an actinic radiation curable composition with actinic radiation wherein the actinic radiation curable composition comprises:
- (A) at least one actinic radiation curable cationically polymerisable compound;
- (B) at least one cationic photoinitiator for component;
- and
- (C) at least one stabilizer which is a complex of a Lewis acid and a Lewis base, provided that the Lewis acid is not a fluorine-containing boron compound and wherein the stabilizer is present in the actinic radiation curable composition in an amount of between 0.001 weight % to 0.3 weight %.
A method for stabilizing an actinic radiation curable composition comprising mixing at least one actinic radiation curable cationically polymerisable compound and at least one cationic photoinitiator with at least one stabilizer which is a complex of a Lewis acid and a Lewis base, provided that the Lewis acid is not a fluorine-containing boron compound.
