Hard vinyl chloride resins are widely used as hard and tough thermoplastic resins, but they themselves have several drawbacks. For example, when hard vinyl chloride resin is used for building materials such as flooring materials or office supplies such as desk mats, there are drawbacks such as hard surfaces, slippery surfaces, and poor cushioning properties.

In order to improve these shortcomings, a method has been proposed in which a layer of soft vinyl chloride resin plasticized with a liquid plasticizer is laminated on a hard vinyl chloride resin molded article (Japanese Patent Application Laid-Open No. 1983-1973-1).

However, in such laminates, the soft vinyl chloride resin layer becomes hard and undergoes dimensional shrinkage due to volatilization of the liquid plasticizer in the soft vinyl chloride resin layer width or migration to the hard vinyl chloride resin molded product layer. The problem was that the laminate warped with the soft vinyl chloride resin layer side facing inside.

On the other hand, soft vinyl chloride resin plasticized with a liquid plasticizer such as dioctyl phthalate has excellent moldability and moderate flexibility, so it is often used for various purposes. Molded products have the disadvantage that dust tends to adhere to them. As a countermeasure to this problem, it has been proposed to laminate a hard vinyl chloride resin thereon, but this has the disadvantage that the laminate also warps in the case of the mouth.

Therefore, it is extremely important from an industrial perspective to improve these defects found in hard and soft vinyl chloride resins. As a result of various studies aimed at solving this problem, the present inventors found that in a laminate consisting of a hard vinyl chloride resin layer and a soft vinyl chloride resin layer, the conventional method used for the soft vinyl chloride resin layer By using ethylene-vinyl acetate-carbon oxide copolymer, which is a polymeric plasticizer that does not volatilize or migrate to other base materials, instead of a liquid plasticizer, there is no warping, and transparency and impact resistance are achieved. It has been found that laminates can be obtained which have improved peeling resistance.

For example, the use of ethylene-vinyl acetate-carbon oxide copolymer as a plasticizer for vinyl chloride resin was reported in
As described in Japanese Patent Application No. 5-50063, the present inventors have developed a method to heat a soft vinyl chloride resin layer and a hard vinyl chloride resin layer plasticized with such a copolymer. By laminating using a laminating method such as pressure molding with a press, high-frequency dielectric heating, thermal bonding with a thermal adhesive roll, or coextrusion coloring, (1) When using a conventional liquid plasticizer, migration of the plasticizer is prevented. However, the ethylene-
When a vinyl acetate-carbon dihydride copolymer is used, no warping occurs at room temperature (1) or even when exposed to the harsh conditions of the accelerated heating test shown in the examples below (2) Both layers do not warp. It has been found that a laminate can be obtained which has strong adhesion to the extent that it does not peel off even in the accelerated heating test shown in Examples below.

Approximately 50 to 200 parts by weight of ethylene-vinyl acetate-carbon oxide copolymer IN resin is uniformly mixed into the soft resin layer per 100 parts by weight of vinyl chloride resin. If the copolymer resin is used in a mixing ratio lower than this, the resin layer will be too hard and sufficient elasticity or anti-slip effect will not be obtained, while if it is used in a ratio higher than this, the resin layer will become sticky. or become easily injured. Note that a commonly used liquid plasticizer can also be used in this soft resin layer, but the proportion thereof does not exceed the mixing proportion of the above-mentioned copolymer resin.On the other hand, The hard resin layer is formed from a vinyl chloride resin alone or a mixture thereof with a plasticizer such as the above copolymer resin or a liquid plasticizer in an amount of about 20 parts by weight or less per 100 parts by weight of M resin.
