Abstract
The present invention is a decorative laminated article comprising an image bearing thermoplastic interlayer wherein the image has been printed on the interlayer using an ink jet printing process, wherein the pigment comprises at least one pigment selected from the group consisting of: PY 120; PY 155; PY 128; PY 180; PY 95; PY 93; PV19/PR 202; PR 122; PB 15:4; PB 15:3; and PBI 7. The interlayer material of the present invention can be, for example, PVB, PET, or polyurethane.
Claims30
A process for obtaining an image-bearing laminate, the process comprising the steps:
- (a) providing a first thermoplastic polyvinyl butyral interlayer sheet having a roughened polyvinyl butyral interlayer surface, the surface having a roughness (Rz) of from about 30 μm to about 60 μm and a Frequency of greater than 0.9 cycles/mm;
- (b) ink jet printing a digital image, using an organic solvent-based, pigmented ink, onto the roughened surface of the first thermoplastic polyvinyl butyral interlayer sheet to obtain an image-bearing thermoplastic polyvinyl butyral interlayer sheet;
- (c) providing a second thermoplastic polyvinyl butyral interlayer sheet;
- (d) placing the second thermoplastic polyvinyl butyral interlayer sheet over the image-bearing surface of the first thermoplastic polyvinyl butyral interlayer sheet;
- (e) providing a third thermoplastic polyvinyl butyral interlayer sheet;
- (f) placing the third thermoplastic polyvinyl butyral interlayer sheet on the side of first thermoplastic polyvinyl butyral interlayer sheet opposite the image-bearing surface;
- and
- (g) laminating the thermoplastic polyvinyl butyral interlayer sheets between two sheets of transparent materials selected from the group consisting of glass or polycarbonate to obtain an image-bearing laminate;
- wherein:
- (i) the pigmented ink (A) has a viscosity of in the range of from about 1 cps to about 30 cps measured at 25° C., (B) does not contain a binder, and (C) comprise at least one pigment selected from the group consisting of Pigment Yellow 120;
- Pigment Yellow 155;
- Pigment Yellow 128;
- Pigment Yellow 180;
- Pigment Yellow 95;
- Pigment Yellow 93;
- Pigment Violet 19/Pigment Red 202;
- Pigment Red 122;
- Pigment Blue 15:4;
- Pigment Blue 15:3;
- and Pigment Black 7;
- (ii) organic solvent is selected from the group consisting of alkylene glycol ether, alkylene glycol ester or mixtures thereof;
- and
- (iii) the resulting image-bearing laminate has a laminate adhesive strength of at least about 1500 psi.
