Title:
ADDITIVE IN PAPER FOR HOT-PRESS FORM AND HOT-PRESS FORM EMPLOYING THE SAME
Document Type and Number:
WIPO Patent Application WO/1993/013925
Kind Code:
A1
Abstract:
Conventionally, inorganic or organic particles are added as additives in paper for a hot-press form for imparting a granite-like pattern so as to form such a pattern. However, when boiled in hot water, innumerable small blisters are produced, and this reduces the quality of products, while it is possible to obtain as additives for forming a pattern tinted paper treated with a thermosetting resin so as to be water resistant and ground into any desirable diameter. In addition, it is possible to select any pattern having spots having in turn any desirable color and size by selecting the color of tinted paper. By employing pattern paper made by adding these additives in paper when making paper it is possible not only to prevent a risk of producing the afore-said blisters but also to form a sharp pattern, and a hot-press form made by using the paper has an image of natural granite.
