Pearl-like decorative paper having suitability for postforming and thermosetting resin decorative sheet

Abstract

The present invention relates to a pearlescent decorative paper and a thermosetting resin decorative board suitable for post-forming processing. Even if the material has a pearlescent appearance, foaming or cracking will not occur during post-forming processing. In the pearlescent decorative paper (10), there is a pearlescent ink layer (3) containing pearlescent pigments on a paper substrate (1), and as the pearlescent pigments, scale-shaped foils covered with mica with titanium dioxide and / or iron oxide are used A pearlescent pigment whose surface is then treated with zirconia hydrate. If the pattern ink layer (2) made of normal ink is provided therein, the design property will be improved. After the pearlescent decorative paper is impregnated with a thermosetting resin such as melamine resin, it is laminated with an adherend (6) such as a backing substrate (4) or a cover paper (5), and thermocompressed to cure the resin. A pearlescent thermosetting resin decorative plate (20) comprising pearlescent decorative paper (10A) cured with resin can be used.

Description

technical field [0001] The present invention relates to a pearlescent (pearl) material suitable for post-forming processing that can be used in various building materials such as desks, dining tables, counter tops, etc., or building interior materials such as furniture, walls, floors, etc. like) decorative paper and thermosetting resin decorative board. Background technique [0002] Thermosetting resin decorative boards represented by melamine decorative boards are generally made of decorative paper printed with patterns on paper substrates, impregnated with thermosetting resins such as melamine resin, and then combined with lining materials or covering paper. The adhesives are combined, and the resin is cured by applying heat and pressure to complete the lamination and integration. In addition, as one of the exterior designs of the decorative board or decorative paper, there is a pearlescent design. It is known that in such pearlescent decorative paper or thermosetting re...

Problems solved by technology

[0004] However, if the appearance of the post-formed product is to have a pearlescent feel, foaming is more likely to occur during the post-formation process than in the case of the usual design. Even if the paper base material is studied as described in Patent Document 3, there is no found to improve foaming

In addition, when the heating during processing is reduced in order to suppress the occurrence of this foaming, the problem of easy cracking will occur.

As mentioned above, in the case of pearlescent design, the suitability for post-forming processing is poor, so there is a problem that it is difficult to commercialize
