Image carrying laminated material

摘要

A method of producing image carrying laminated material comprises the steps of forming an image by ink jet printing on a first surface of a sheet of interlayer using solvent based ink, solvent based paint or solvent based dye system(s), interposing an interlayer comprising the sheet of interlayer between two sheets of material, and joining the two sheets of material to form the laminate by activating the interlayer. In addition, a method of producing an image carrying laminated safety glass comprising the steps of mechanically stabilizing a sheet of heat softening interlayer, forming an image on a first surface of the interlayer by ink jet printing using solvent based ink, solvent based paint or solvent based dye, removing the mechanical stabilization, interposing an interlayer comprising the sheet of heat softening interlayer between two sheets of glass and joining the two sheets of glass to form the laminated safety glass by heating the interlayer. Further, an image carrying laminated sheet, comprising two sheets of material joined by an interlayer comprising a sheet of interlayer having an image formed on a first surface of the interlayer by ink jet printing using solvent based ink, solvent based paint or solvent based dye system(s).

主权项

1. A method of producing an image carrying laminated material, comprising:
providing a sheet of interlayer subject to stretching under tension, mechanically stabilizing the sheet of interlayer such that the sheet of interlayer is substantially not under tension, forming an image on a first surface of the mechanically stabilized sheet of interlayer, removing the mechanical stabilization, curing the image on the interlayer at ambient temperature for 24 hours or more, interposing the sheet of interlayer with the image cured between two sheets of material, and joining the two sheets of material by activating the sheet of interlayer; wherein the image is formed by ink jet printing on the first surface of the sheet of interlayer with a solvent based pigmented ink system, the solvent etches the first surface of the interlayer sheet such that a printed pigment is not on the interlayer surface immediately contacting the adjacent sheet of material; the mechanical stabilization prevents the sheet of interlayer from stretching or deforming during the ink jet printing; the sheet of interlayer is a polyvinylbutyral sheet or a polyether based aliphatic thermoplastic polyurethane sheet; and the two sheets of material are glass.
