Description of the Related Art Conventionally, when a decorative sheet is further laminated and adhered to the surface of a thermosetting resin decorative board, it is difficult to bond the decorative sheet to the cured resin layer. Laminated and bonded. For example, a decorative sheet made of a thermoplastic resin may be laminated and adhered simultaneously with molding via an adhesive layer, an easy-adhesion primer layer and the like as required (for example, JP-A-60-122149, JP-A-3-218832). And Japanese Patent Laid-Open Publication No. Hei 4-37508), and a decorative sheet using heat-resistant and dimensionally stable paper is laminated and adhered simultaneously with molding (for example, Japanese Patent Publication No. 26-4540). JP-A-53-
No. 9872, Japanese Patent Application Laid-Open No. 62-152733, etc.) are known.

発する。この現象は成形条件のバラツキ、シートのロッ
トによるバラツキによっても変化するので品質が安定し
なかった。In the former described in the prior art, since the thermoplastic resin is softened by heating, the decorative sheet is deformed by heat and stress during molding of the thermosetting resin decorative board. Frequently, the pattern collapses or causes unevenness. Since this phenomenon varies depending on variations in molding conditions and variations depending on sheet lots, the quality is not stable.

題点もあった。Further, in the case of the latter, distortion or flow of the picture does not occur, but on the other hand, printing is not as clear and precise as the former because of the unevenness and absorption of the fiber of the paper. This tends to cause unevenness in the picture. This tendency is particularly pronounced when the picture is provided solidly over the entire surface. In addition, since the resulting decorative board has no flexibility and flexibility, there is a problem that cracks and cracks are easily generated when a force such as a bending force or an impact force is applied.
【０００５】そこで、熱硬化性樹脂からなる化粧シート

着性が不十分であり、また化粧板全体が上記のものより
更に硬くなり、補強したり応力を逃がすものもないた
め、曲げ等により容易に亀裂や割れを生じることから実
用化の可能性はない。Therefore, it is conceivable to use a decorative sheet made of a thermosetting resin. However, the cured thermosetting resin sheet has no chemical reactivity and thus has insufficient adhesion to other layers of the decorative board. In addition, the decorative panel as a whole is harder than those described above, and there is nothing to reinforce or release the stress. Therefore, cracks and cracks are easily generated by bending or the like, so that there is no possibility of practical application.

Resin prepolymer, curing catalyst, accelerator, curing retarder,
A chop strand obtained by applying a resin compound obtained by kneading an air desiccant or the like and a filler such as calcium carbonate, talc, clay or the like by knife coating or the like, and then cutting a glass roving obtained by bundling glass fibers. After spraying, a resin compound similar to that applied to one surface of the first separator film is applied to one surface of the second separator film by another application method, and then the first separator film and the second separator film are applied. The separator film is overlapped so that the resin compound application surfaces of both separator films face each other via the chop strands on which the resin compound is sprayed, and the resin compound is impregnated and removed from the sprayed chop strands by pressing with a roll. A method of foaming, humidifying and curing is used. The resin used for producing the SMC is not particularly limited, but usually includes many unsaturated polyesters and epoxies.

So-called stamping molding, in which the laminate is inserted and pressure or heat and pressure is applied by both dies, is used. The heating is performed to initiate or accelerate the crosslinking or polymerization reaction itself of the thermosetting resin, and may be omitted if heating is not necessary. The heating temperature depends on the type of resin,
Although it is determined by the composition, it is usually about 40 to 150 ° C.

Is dissolved and the printed pattern flows. However, in the thermosetting resin decorative sheet of the present invention, the nonwoven fabric laminated on the thermoplastic resin sheet has the adhesion performance due to the impregnation action (anchoring effect) and the dimensional stability to prevent the resin flow.
