ABSTRACT:
A prepolymer for use in preparing photocurable compositions is prepared by reacting an aliphatic diisocyanate having terminal isocyano groups and at least one alkyl side chain with a hydroxy-, mercapto- or amino-containing olefinically unsaturated compound. This prepolymer is compounded with a photosensitizer and, optionally, a polymercaptan to prepare photocurable compositions.
