Description

The present invention relates to multilayer sheet bodies made of paper or similar material.

To make a cutting template on the top layer of a Number of layers of textile material, it is known in the textile industry to use sheet material, on the one hand with a photosensitive layer and on the other with a thermoplastic layer Adhesive is equipped.

In current practice, a variety of

Stencils made of paper or other non-transparent ones Materials made according to the parts of the articles of clothing. These stencils are made on paper or something similar Material placed on the upper side with a photosensitive layer and on the lower side with equipped with a thermoplastic adhesive. Then a light source is switched on, which is photosensitive Layer exposed and developed with moist ammonia gas. The exposed and developed diazotype material is now placed on one or more layers of textile material and on the first layer by means of a heat source, for example an iron attached. The layers of textile material can now be cut along the edges of the template whereupon the material, which is provided with a stenciled pattern, is removed from the first layer of the textile material ' is separated .. From the parts thus obtained, articles of clothing can be made.

According to that described in Dutch patent specification 70,254 In the process, the photosensitive material is already bonded to the textile material at the time of exposure. In this process, the light source is also used for heat treatment. A disadvantage of this procedure is that that the light source, which, by the way, was not described in more detail, caused a very large increase in temperature (100 to

The present invention relates to a material for textile

Textile fabric adheres, and a light-! have a sensitive coating developed by heat « to create a light induced latent image of the stencil. When heated, the back becomes < '' the stencil is brought into contact with tissue, the image of the stencil is developed and the material at the same time: glued to the fabric. . ,

Developing the image and attaching the pattern on the tissue takes place in one operation.

You thermal Development takes place by reducing the acidity or the formation of an alkaline reaction medium under the action of heat. For example, zinc acetate is used in basic zinc salts, urea in basic nitrogen compounds and trichloroate in chloroform and carbonates which decomposes the coupling reaction of the diazo component promote with the coupling component.

The photosensitive layers of Examples I, II and III are made with the adhesive rails described in the examples or similar layers applied ".
