METHOD OF PRODUCING DECORATIVE INTERPLAYER FOR LAMINATED GLASS

摘要

Method comprises: (a) forming a transfer sheet having a desired printing pattern printed in ink capable of dyeing a interlayer made of a thermoplastic resin for laminated glass, on a transfer sheet substrate; (b) applying a solvent capable of softening to some extent the vehicle of the printing ink and the interlayer to the printed pattern surface of the resulting transfer sheet and/(or) the surface of the interlayer; (c) transferring and infiltrating the printed pattern into the surface of the interlayer by superposing the surface of the printed pattern or the interlayer through the coated surface of the solvent and pressing them at a temp. lower than the glass transition point of the interlayer; and (d) obtaining the decorative interlayer for laminated glass by peeling off the transfer sheet substrate from the interlayer and drying.
