Hot melt coating compositions for printed sheets and coated,lenticulated sheets having 3-d appearance
Abstract
Abstract FLEXIBLE SHEETS (SUCH AS PAPER) HAVING A THREE DIMENSIONAL (3-D) APPEARANCE HAVE A PRINTED STEREOGRAPHIC IMAGE COATED WITH A HOT MELT COATING COMPOSITION HAVING ON ITS SURFACE A LENTICULATED PATTERN, SAID COATING COMPOSITION BEING ESSENTIALLY (50-100%) COMPOSED OF MALEATED POLYETHYLENE. ABOUT 5 TO 45% OF THE COATING COMPOSITION MAY BE A COPOLYMER OF ETHYLENE AND EITHER AN ALKYL (18 CARBONS) ACRYLATE OR A VINYL ALKANOATE (1-8 CARBONS). SUCH COATING COMPOSITIONS AS CONTAIN 5-45% COPOLYMER (70 TO 95% ETHYLENE-30 TO 5% ETHYL ACRYLATE) HAVE EVEN GREATER ADHESION TO BOTH PAPER AND INK-PRINTED AREAS, AND ALSO OTHER DESIRABLE PROPERTIES, E.G. RESIST BLOCKING, STAIN RESISTANT, WITHSTAND FOLDING, RESIST STRESS CRACKING, ABRASION RESISTANT, POSSESS INHERENT STABILITY WITH LITTLE OR NO ADDITIVES, ETC.
