Claim 1
Independent Claim
60 words
A dye donor sheet for transferring dye donor material in an imagewise manner by means of thermal dye transfer printing, said sheet comprising a non-porous backing material having on at least one major surface thereof a thermal dye transfer layer comprising a dye in a chlorinated polyvinyl chloride resin or a mixure of chlorinated polyvinyl chloride and polyvinyl chloride resin.
Claim 2
Dependent Claim
60 words
A dye donor sheet for transferring dye donor material in an imagewise manner by means of thermal dye transfer printing, said sheet comprising a non-porous backing material having on at least one major surface thereof a thermal dye transfer layer comprising a dye in a chlorinated polyvinyl chloride resin or a mixure of chlorinated polyvinyl chloride and polyvinyl chloride resin.
