The present invention relates to a vinyl chloride resin composition and molded product with excellent slip properties and transparency. Conventionally, vinyl chloride molded products containing plasticizers, especially films and sheets, had a problem in that the surface became sticky due to the influence of the plasticizer, making it difficult to work during secondary processing of the films and sheets. In order to improve the workability during secondary processing, that is, to improve the slip properties of the film, attempts have been made to add lubricants to the film, add fine fillers, and embossing the surface with a satin finish, but adding lubricants to the film surface There is a problem that leaching of the lubricant inhibits printability, that is, the adhesion of printing ink, and addition of fillers and embossing inhibits transparency, resulting in a film with excellent slip properties, transparency, and printability. Nothing could be done. The object of the present invention is to provide a soft vinyl chloride resin composition and a molded product that have improved slip properties, transparency, and printability, and have improved these drawbacks. That is, the present invention relates to a first invention relating to a soft vinyl chloride resin composition obtained by adding 1 part by weight or less of a crosslinked vinyl chloride resin having a gel fraction of 90% or less of tetrahydrofuran to 100 parts by weight of a vinyl chloride resin, and a molded version thereof. This relates to molded products. There are various patents regarding compositions and molded products related to cross-linked vinyl chloride resin, but all of these patents are aimed at obtaining matte products.The present invention, by adding an appropriate amount of cross-linked vinyl chloride
A molded product with excellent transparency and good slip properties can be obtained, and in terms of physical properties, it has the same practical performance as conventional vinyl chloride resin. The reason why the present invention has excellent slip properties is that the cross-linked vinyl chloride resin forms a slight convex shape on the surface of the molded product, which prevents the surfaces of the molded products from coming into close contact with each other, and the cross-linked vinyl chloride resin The light refractive index of is almost the same as that of vinyl chloride resin, and there is little scattering of light due to the difference in refractive index, unlike when an inorganic filler is added, and therefore molded products with excellent transparency can be obtained. The crosslinked vinyl chloride resin that can be used in the present invention includes a vinyl chloride monomer or a vinyl chloride monomer and a copolymerizable monomer copolymerizable therewith, and a polyvinyl chloride resin having two or more ethylenic double bonds in the molecule. It is a vinyl chloride copolymer consisting of a functional compound, and

56-5843, JP 56-11916, JP 56-79141, JP 56-81325, JP 56-142025, JP 54-45422, etc. You can use the items listed in Cross-linked vinyl chloride resin contains a gelling component of tetrahydrofuran, and resins with a gel fraction of 90% or less can be used; those with a gel fraction higher than this may cause poor appearance due to sticking eyes (residual particles) in the molded product. It is easy and inappropriate. The lower limit of the gel fraction is not particularly limited, but considering the addition efficiency of the cross-linked vinyl chloride resin, it is not advantageous to use a material with a very low gel fraction, so a gel fraction of 10% or more is preferable. It's a rate thing. The amount added should be selected in relation to the gel fraction.
When using a product with a high gel fraction compared to a product with a low gel fraction, the amount added is smaller, and the maximum amount added is 1
Parts by weight. If the amount added is more than this, the transparency will decrease, which is not preferable. A particularly preferred amount is such that the value of (gel fraction/100) x (parts by weight added) is 0.5 or less. The transparency of a molded product can be evaluated by its haze value. The smaller the haze value, the better the transparency. As the haze value increases, the light rays will be more diffused, and the image of the object on the opposite side of the molded product will become more visible. appears distorted, and transparency decreases. If the haze value is 10% or less, there is little distortion of the image and it has practical transparency. When it becomes larger than 10%, practical transparency is lost. The gel fraction of the present invention is determined using a Soxhlet extractor.
It was determined from the weight of the extraction residue extracted with hot tetrahydrofuran for 22 hours and separated using a 350 mesh filter. The vinyl chloride resin used in the present invention includes polyvinyl chloride and copolymers of vinyl chloride and other monomers, such as ethylene vinyl, vinyl acetate, vinyl ether, maleic ester, and the like. It also includes products blended with other polymers. The type of plasticizer to be added is not limited in any way, and any plasticizers commonly used for vinyl chloride resins can be used. The amount added is also not limited. Furthermore, stabilizers, ultraviolet absorbers, antioxidants, pigments, inorganic substances, antistatic agents, etc. can be added as necessary. The present invention can be used in desk mats, medical chart holders, document holders for stationery, agricultural films, partition curtains, etc., and provides products with excellent slip properties and transparency. The present invention will be described in detail by way of examples. 0.12 when calendered with the composition shown in Table 1.
A film with a thickness of m/m was prepared and its transparency and slip property were evaluated. The numbers shown are parts by weight.
Numbers 1 to 4 indicate examples of the present invention, and numbers 5 to 6 indicate comparative examples.

(b) Slip property Cut each film into 5cm x 10cm pieces, stack 30 films on top of each other, place a 500g load on top of it, leave it for 8 hours at 30°C, and then squeeze the 30 films with both hands to peel them off from each other. We investigated the ease of The ease of peeling was ranked into 5 levels, with items that peeled off with little force being rated 5, items that did not peel at all as 1, and the intermediate grades were rated 4, 3, and 2.
