なる。In recent years, non-impact printers such as xerographic printers have been increasingly used to record information entered into computers, etc. on sheets. In those that form a printed image, the printed image is fixed by a heating method. Therefore, in order to seal or stitch the printing sheet after printing, it is necessary to apply a heat-sensitive adhesive that softens and exhibits adhesive properties to the sealing part in advance, or the microcapsules are destroyed by heat and the internal parts are removed. When a type of heat-sensitive adhesive that exhibits adhesive properties by leaching out of the adhesive is applied, the adhesive tends to soften due to heating during fixing and adhere to the printer. Similarly, when the sheets are continuous paper, stacking causes the sheets to stick together, making it difficult to feed the sheets to the printer.

とがない。To prevent this, if a large amount of inorganic powder or the like is used, the adhesiveness will be reduced. In the present invention, even if the adhesive component outside the microcapsules is softened by heating during fixing, a large amount of microcapsules can be blended so as not to exhibit tackiness. Even if a large amount of microcapsules are blended, since the capsules contain an adhesion aid (adhesive component if necessary), by destroying the microcapsules during adhesion, the external adhesive component can be activated, resulting in poor adhesion. No loss of adhesion.

A particularly useful adhesive component in preparing pressure sensitive adhesives is a natural rubber-based adhesive component. Since natural rubber is less susceptible to softening due to heat and has excellent thermal stability, in combination with the effects of the microcapsules of the present invention, even more excellent results can be obtained. Examples of other adhesive components useful as pressure sensitive adhesives include styrene-ptadiene rubber, acrylic polymers, vinyl acetate polymers, polyvinyl alcohol, and the like.
