Abstract
Linerless label stock is produced from a single substrate utilizing a coating machine by moving the substrate through the coating machine and applying a tie coating to the substrate first face, a release coating to the substrate second face, and a pressure sensitive adhesive to the tie coating. The release coating comprises a mixture of (a) about 55 to about 95 parts by weight of a first acrylated polysiloxane having the formula I: ##STR1## wherein R is a C.sub.4 -C.sub.2 alkyl group, m is about 40 and n ranges from about 8 to about 12; PA1 b) about 5 to about 45 parts by weight of a second acrylated polysiloxane having the formula II: ##STR2## wherein R is a C.sub.4 -C.sub.12 alkyl group, m is about 180 and n ranges from about 8 to about 12; and PA1 c) about 2 to about 6 parts by weight of a photoinitiator.
