INTRODUCTION

Recently in the paint and printing ink fields resins which cure
by exposure to high energy radiation are becoming more widely
used.

These resin systems have many advantages such as fast curing,
fine patterning due to easy masking; improved dimensional stability
due to low temperature curing; they contain no solvents thus
eliminating environmental problems and the curing process is
energy saving. Despite these advantages not all the demanded film.
properties can always be achieved ie. high elongatIon, uniformity
of cure in depth; insufficient cure in areas of the film not
exposed to radiation etc. Thus hybrid radiation curing systems
have been introduced to overcome these problems. The various
possible UV radiation curable hybrid systems are shown in figure
1. Our research in this area has been focused on the behavior of
the radiation curing of hybrid systems utilizing a thermal curable.
