Examples include xybutyl vinylvinal, methacrylic acid, acrylic acid, monobutyl maleate, undecylenic acid, etc. Of course, two or more types of these comonomers can be used. These comonomers are preferably contained in the crosslinked resin in an amount of 0.5 to 1% by weight, and the hydroxyl group or carboxyl group of the comonomer contributes to crosslinking of the crosslinkable resin. If the comonomer content is less than 0.5% by weight, the crosslinking reaction will not occur sufficiently, and if it is more than 1% by weight, the excellent physical properties of the crosslinkable resin itself may not be expressed, depending on the mixing ratio of PVC. However, when used as a decorative material, undesirable results tend to occur. Therefore, the proportion of PVC and crosslinkable resin in the resin composition is such that the latter accounts for 5 to 95% by weight, preferably 30 to 7% by weight, based on the total amount of the two resin components.

The purpose of the present invention is to laminate the resin composition and the decorative substrate, but the lamination method is not particularly limited. For example, only the resin composition is shaped into a desired shape and heated to gel, and then the blowing agent is decomposed. There is also a method in which an elastic solid is produced by heating above the temperature and foaming, and then laminated onto a decorative substrate using an adhesive or the like. Alternatively, the foam may be laminated on the foaming agent and then heated to a temperature higher than the decomposition temperature of the foaming agent to foam the foam.

は、ゲル化と同時に加熱発泡させることを防げるもので
はない。In the method of the present invention, a resin composition is coated and laminated on a decorative substrate 2 by the method described above. For example, if the composition is plastisol, the composition may be heated at a temperature of 140°C or lower for an appropriate period of time, preferably 20°C.
~4 inkstone sand, or 160 if the composition is an organosol
oo or less for an appropriate time, preferably 50 to 7 sand.
The resin composition is gelled by heating for a while, and if necessary, another type of resin composition is further laminated on the gelled product, and the operation of the same machine is repeated. The laminate is then foamed by heating at a temperature of 160 to 2200C, particularly 180 to 200C, for 30 to 49 degrees centigrade. According to the method of the present invention, a certain degree of crosslinking progresses while the resin composition is gelled, and crosslinking and foaming progress simultaneously during the subsequent heating and foaming. When the gelation conditions before foaming are severe, that is, when the gelation temperature is high or the gelation time is long, the surface of the resin composition tends to become flat when heated and foamed. In this way, the decorative material 1 is produced, in which the elastic solid 3 obtained from the resin composition is laminated on the decorative base 2. Of course, the method of the present invention cannot prevent heating and foaming from occurring simultaneously with gelation.

てソフトである。Further, when the decorative substrate is processed with embossing or the like, the embossing pattern is exaggerated and expressed by heating and foaming the resin composition, resulting in an extremely beautiful decorative material. Furthermore, when the uneven pattern on the decorative base is made of a synthetic resin composition containing a chemical foaming agent, when the resin composition applied thereon is heated and foamed, the uneven pattern also foams at the same time, making the decoration even more deeply carved. wood is obtained. Another feature of the method of the present invention is that it has particularly good reproducibility. As mentioned above, the decorative material of the present invention has an extremely beautiful appearance and is extremely soft to the touch.

0) and vinyl chloride base resin in a ratio (weight ratio) of 1:1, 10 parts by weight of the mixed resin, 8 parts by weight of dibutyl phthalate, 3 parts by weight of ca-zn stabilizer, and 1 part by weight of calcium carbonate. 1 part by weight of azodicarbonamide, 1 part by weight of an isocyanate crosslinking agent (trade name PAP1, manufactured by Kasei Upjohn Co., Ltd.), and 2 parts by weight of zinc white were thoroughly mixed in a ribbon blender to form a resin composition. .
該組成物をェンボス加工を施した紙及び塩化ビニルフィ
ルム上に約18叫の厚さ特定模様にスクリーン印刷を施
こし、熱風炉中で130qoで3の砂・間ゲル化を行な
った。The composition was screen printed on embossed paper and vinyl chloride film in a specific pattern with a thickness of about 18 cm, and gelled with sand at 130 qo in a hot air oven.
次いでこれらを赤外線ヒーターを装備した加熱炉で20
0℃、3現砂間加熱発泡ごせた。得られた装飾材は両方
共印刷された模様と同一で、弾性固体の表面には細かい
珍奇なしわが発生し立体感がある手触り等すこぶる良好
な感触であった。実施例 2
塩化ビニルベーストレジン10の重量部にフタル酸ジオ
クチル8の重量部アゾジカルボンアミド5重量部を混合
した組成物を紙の上に特定模様をスクリーン印刷し、1
3000で25砂間ゲル化を行なった。These are then heated in a heating furnace equipped with an infrared heater for 20 minutes.
The product was foamed by heating at 0°C between three layers of sand. Both of the obtained decorative materials had the same pattern as the printed pattern, and the surface of the elastic solid had fine and unusual wrinkles, giving it a three-dimensional feel and a very good feel. Example 2 A composition prepared by mixing 10 parts by weight of vinyl chloride-based resin, 8 parts by weight of dioctyl phthalate, and 5 parts by weight of azodicarbonamide was screen-printed in a specific pattern on paper.
3000 and performed gelation between 25 sands.
この上にナイフコーターでもつて約20叫の厚さに実施
例1で用いた樹脂組成物に青色顔料を若干混合したもの
を塗布し、実施例1を同様の方法でゲル化後加熱発泡さ
せた。得られた装飾材は極めて美しく、スクリーン印刷
を施した部分が大きく発泡して彫を深くし、他の部分に
は小じわが発生していた。そして紙上の弾性固体を指で
長時間圧縮したのち、その圧を開放するとただちに復元
した。A mixture of the resin composition used in Example 1 and a slight amount of blue pigment was coated on this with a knife coater to a thickness of about 20 mm, and after gelling and foaming was carried out by heating in the same manner as in Example 1. . The resulting decorative material was extremely beautiful, with large bubbles and deep carvings in the screen-printed areas, and fine wrinkles in other areas. Then, after compressing the elastic solid on the paper for a long time with fingers, it immediately returned to its original state when the pressure was released.
