For decorative sheets that are mainly used as surface materials for furniture, etc., base paper for decorative sheets with a basis weight of about 55 to 100 g/m 2 is impregnated with diallyl phthalate resin at a rate of about 50% by weight of the base paper for decorative sheets. The prepreg sheet obtained by solidification is layered with backer paper impregnated with diallyl phthalate resin or phenol resin, and this is then hot-press molded, or on the back side of a thermoplastic resin sheet with a printed pattern. A material made by bonding and laminating thermoplastic resin sheets such as hard vinyl chloride resin sheets is used.

The decorative sheet obtained by hot-pressing the above-mentioned prepreg sheet and backer paper impregnated with diallyl phthalate resin or phenolic resin requires high temperature and pressure during the manufacturing process, so it is difficult to manufacture. Not only is the process complicated and the manufacturing cost high, but the decorative sheet itself has the drawbacks of lacking flexibility. In addition, decorative sheets made by adhering and laminating thermoplastic resin sheets with printed patterns and thermoplastic resin sheets such as hard vinyl chloride resin sheets have insufficient hardness on the surface of the decorative sheet, resulting in poor robustness. In addition, strong adhesive strength cannot be obtained between the hard vinyl chloride resin sheet forming the back layer of the decorative sheet and the decorative board base material such as separately manufactured plywood or particle board. In contrast, the present invention has excellent properties in terms of surface smoothness and surface hardness, is highly flexible, is easy to manufacture, and is compatible with decorative laminate base materials such as plywood and particle board. To provide a decorative sheet in which strong interlayer strength is formed between the layers.

The specific structure of the decorative sheet of the present invention will be explained. In the drawings, reference numeral 1 indicates one embodiment of the decorative sheet of the present invention, which has a decorative layer 7 and a basis weight of 80.
A reinforcing layer 8 made of hardened synthetic rubber latex impregnated with paper of ~400 g/m 2 is bonded and laminated with an adhesive layer denoted by numeral 9. The layer 7 is formed of a thin paper 5 having a basis weight of 10 to 50 g/m 2 and has a printed pattern layer 4 consisting of a solid printed layer 2 and a patterned printed layer 3. The thin paper 5 used for the decorative layer 7 has a basis weight of 10 to 50
g/m 2 of printing paper for construction materials, pure white paper, reinforced printing paper made of paper mixed with synthetic resin, etc., and the printed pattern layer 4 applied to the thin paper 5 has a pattern suitable for the field in which the decorative sheet is used. Consists of a printed pattern,
For example, it can be appropriately formed by gravure printing, gravure offset printing, lithographic offset printing, dilithography, letterpress printing, intaglio printing, jet printing, silk screen printing, electrostatic printing, etc. Examples of the resin applied to or impregnated into the thin paper 5 having the printed pattern layer 4 to form the curable synthetic resin layer 6 include unsaturated polyester resin, diallyl phthalate resin, epoxy resin, phenol resin, urethane resin, and melamine resin. Furthermore, mixed resins of two or more of these may be used, with acrylic urethane resins and polyurethane resins being particularly suitable. The curable synthetic resin layer 6 usually weighs 2 to 30 g (dry)/to the thin paper 5 having the printed pattern layer 4.
m 2 , preferably at a rate of about 3 to 10 g (dry)/m 2 , is applied or impregnated, and is formed by curing. Note that when applying or impregnating thin paper with the curable synthetic resin, a solvent such as ethyl acetate, methyl ethyl ketone, toluene, etc. is used as necessary. When obtaining the decorative layer 7, the means for applying the curable synthetic resin to the thin paper include, for example, natural roll coating, reverse roll coating, gravure coating, bar coating, spray coating, mesh roll coating, flow coating, knife coating,
Screen coat, bottom coat, etc. are used. The paper used for the reinforcing layer 8 has a basis weight of 80 to 400.
g/ m2, preferably 200 to 350 g/ m2 ,
For example, SBR, CR, BR,
Impregnated with synthetic rubber latex such as NR and NBR,
By solidifying, the reinforcing layer 8 is formed. In addition, for papermaking, impregnation rate = (weight of entire impregnated paper - weight of papermaking) x 100 / weight of entire impregnated paper so that the impregnation rate (%) is about 20 to 50. , the synthetic rubber latex is impregnated and solidified. The adhesive for bonding and laminating the decorative layer 7 and the reinforcing layer 8, that is, the adhesive layer 9, is preferably made of epoxy resin, urethane resin, or the like.
Adhesion methods such as dry lamination or wet lamination at a roll temperature of about 70 to 150°C are used.

In the decorative sheet 1 of the present invention, the reinforcing layer 8 laminated on the back surface of the decorative layer 7 is
The reinforcing layer 8 has the effect of absorbing irregularities on the adhesion surface of the decorative laminate base material when it is attached to a decorative laminate base material such as separately manufactured plywood or particle board. In addition to this, it also acts as a reinforcement for the decorative sheet. Therefore, even if an unexpected situation occurs in which a scratch occurs from the decorative layer 7 side of the decorative paper sheet 1, this scratch can be prevented from penetrating into the interior of the decorative board. Further, in the decorative sheet 1 of the present invention, since the aforementioned reinforcing layer 8 is formed of paper made by impregnating and solidifying synthetic rubber latex, the decorative sheet has flexibility, such as winding and rolling. Since it is flexible enough to be returned, it has excellent characteristics in terms of continuous production and handling workability. Furthermore, in the decorative sheet 1 of the present invention, a thin paper 5 having a printed pattern layer 4 and having a basis weight of 10 to 50 g/m 2
The surface smoothness and surface hardness of the decorative layer 7 obtained by coating or impregnating and hardening a curable synthetic resin on the paper, and the hardening of the synthetic rubber latex impregnated into the papermaking paper with a basis weight of 80 to 400 g/m 2 The reinforcing layer is also suitable for adhesion to the separately manufactured decorative laminate base material surface.
