ABSTRACT:
Reclaimable overhead transparencies for plain paper copiers are obtained by strongly adhering particulates having a large mean particle size to a transparent base sheet. A transparent, polymeric antistatic binder composition which does not substantially gel or yellow upon heating to reclamation temperatures and a glycidoxy silane are used to strongly adhere the large particulates to the base sheet. The polymeric antistatic binder composition is a mixture of an acrylic polymer or copolymer with an antistatic copolymer. The use of large particulates and the use of the mixture of an acrylic polymer or copolymer and an antistatic copolymer improves antistatic properties without the need for yellowing, foul-odor producing amounts of nitrogenous antistatic agents or gel-forming amounts of cross-linking agents which would adversely affect reclaimability. An emulsified wax is included in the coating composition to reduce the static coefficient of friction of the overhead transparency. The coating composition may be applied in-line to the transparent base sheet to obtain an image-recording surface coating comprising: a) from about 60% by weight to about 85% by weight of the polymeric antistatic binder composition, b) from about 5% by weight to about 20% by weight of a glycidoxy silane, c) from about 3% by weight to about 12% by weight of a wax, and d) from about 3% by weight to about 15% by weight of a particulate material having a mean particle size of from 4 .mu.m to 15 .mu.m, preferably from 7 .mu.m to 12 .mu.m, the weight percentages of components a) through d) adding up to 100%. The reclaimable image receptive transparencies exhibit anti-newton ring properties and may be used as layout montage material, and in solid ink jet printers or electrostatic printers.
