に困難がある。(Prior art) Regarding organopolysiloxanes for release paper, so-called addition reaction type organopolysiloxanes consisting of alkenyl group-containing organopolysiloxanes, organohydrogenpolysiloxanes, and platinum catalysts are widely used, and these are It is said to be suitable for items with relatively low peeling force, such as labels, tapes, wallpaper, and decals, but
In fields that require a large peeling force, such as engineering paper and asphalt wrapping paper, there are significant restrictions on its use, making it difficult to put it to practical use.

Attempts have been made to improve releasability by incorporating fillers such as silica, but these tend to cause unevenness and increased viscosity of the coating solution, and are not practical as they have low coating properties. do not have.

ことが難しいという欠点がある。In addition, it is difficult to blend resins and fillers other than siloxane into the addition reaction type organopolysiloxane compositions described above, as in the condensation reaction type compositions described above.
Furthermore, compositions in which the blending ratio of each component and the radical species of organosiloxane as the main component are changed also have extremely large changes in peeling force over time, making their use inconvenient. A method of adding a toluene-soluble copolymer consisting of O0.5 (R represents a monovalent hydrocarbon group) and a siloxane unit represented by 5in2 has also been proposed (see JP-A-52-86985); Since most of this copolymer does not cure, it has the disadvantage of greatly reducing the adhesive strength and tack of pressure-sensitive adhesives. Attempts have also been made to use atoms or groups that contribute to the curing reaction, and although this can significantly reduce the change in peel force over time due to adhesive bonding, this organopolysiloxane The peeling force of the treated substrate itself over time is extremely large, and there is a drawback that it is difficult to maintain the initial peeling force or other peeling forces.

ものとして有用とされる。(Effects) The composition of the present invention is said to be useful for producing release paper, and this composition is applied to the surface of paper, plastic paper, etc. as a base material for producing release paper, and is heated and cured to form the base material. When a cured film is formed on the surface, this cured film exhibits excellent releasability, but this releasability does not change over time, and the adhesion and residual adhesive strength are also excellent. By changing the mixing ratio of polysiloxane A and polysiloxane B in the components, the release force can be freely adjusted, which has the advantage that a release paper having a desired release force can be easily obtained. It is something that has
Therefore, this product is useful as a material that imparts releasability to process paper, asphalt wrapping paper, etc., which have been difficult to treat with conventional products.
