Heat insulated base layer protects embossed pattern of refractive veins

摘要

An object structure having patterns of refractive veins thereon is provided, in which a heat insulated base plate 21 capable of combining with object major body 1 is provided, then a first base layer 22, a soft material layer 23 which can absorb pressure or stress variation, an aluminium film layer 24 having embossed veins thereon, a second base layer 25. An embossing process is conducted on the second base layer and then a pattern layer is printed thereon. A transparent protection layer is overlaid on the pattern layer for protecting the colours thereof. The heat insulated base plate having pattern design thereon can be combined integrally with the object major body by injection molding process, and pattern integrity can be ensured during injection molding by means of the heat-blocking effect obtained from the heat insulated base plate.
