Abstract
Abstract A process comprising solution interpolymerizing a pressuresensitive resin containing an acid-epoxy monomer system, formulating the interpolymer solution with the 1,3bis(dimethylamino)-2-hydroxypropane and coating the solution on a substrate to obtain a film of pressure-sensitive resin thereon. The pressure-sensitive film possesses cohesive strength and exhibits low release values from silicone coated release paper.
