A transfer-type pressure sensitive adhesive tape containing a pressure sensitive adhesive layer on a support, which is characterized in that ramentum particles are incorporated in the pressure sensitive adhesive layer for the purpose of providing a transfer-type pressure sensitive adhesive tape wherein the pressure sensitive adhesive layer can surely be cut off at the desired position upon transfer thereof under sufficiently keeping adhesive force to a receiving object such as a paper surface and running ability without using any specific pressure sensitive adhesive agent by selecting particles to be added to the pressure sensitive adhesive layer.

Transfer-type pressure sensitive adhesive tape

A pressure-sensitive correction tape is provided which comprises a foundation, a masking layer and a pressure-sensitive adhesive layer stacked on the foundation in this order, the masking layer comprising a masking agent, a polymer having rubber elasticity and an ester compound which is liquid at ordinary temperature and has a boiling point of not less than 130&deg; C. at ordinary pressure.

Pressure-sensitive correction tape

A pressure-sensitive magnetic transfer recording medium comprising a support and a pressure-sensitive transferable magnetic ink layer provided on the support, the pressure-sensitive transferable magnetic ink layer comprising a particulate magnetic substance, a resin and an oily substance, the resin comprising a cellulose acetate butyrate resin having a number average molecular weight of 2.0.times.10.sup.4 to 5.0.times.10.sup.4 and a glass transition point of 100.degree. to 140.degree. C., the oily substance being compatible with the cellulose acetate butyrate resin, and the mixing ratio of the cellulose acetate butyrate to the oily substance being from 3:10 to 7:5 by weight, wherein the oily substance is at least one member selected from the group consisting of an adipic acid ester, a sebacic acid ester, an azelaic acid ester and a trimethylolpropane fatty acid triester.

Pressure-sensitive magnetic transfer recording medium

A pressure-sensitive magnetic transfer recording medium comprising a support and a pressure-sensitive transferable magnetic ink layer provided directly or indirectly on the support, the pressure-sensitive transferable magnetic ink layer comprising a particulate magnetic substance, a titanate type coupling agent having a solubility parameter of 8.8 to 10.6 (cal/cm.sup.3).sup.0.5 and a cellulose acetate butyrate resin. The magnetic transfer recording medium produces printed magnetic images which can be read with high reliability by means of MICR.

A heat-melt transfer recording medium including a foundation, and a release layer, a barrier layer and a colored ink layer provided on the foundation in that order from the foundation side, the release layer including a wax-like substance, the barrier layer being a substantially colorless layer including a thermoplastic resin and containing substantially no wax-like substance, and the colored ink layer including a vehicle containing not less than 50% by weight of a thermoplastic resin. The transfer recording medium has excellent transfer sensitivity and produces print images having excellent smear resistance, abrasion resistance and alcohol resistance.

Heat-melt transfer recording medium

A thermal transfer recording medium comprising a foundation and a thermal transfer ink layer provided thereon, said thermal transfer ink layer containing the particles of a silicone compound. The recording medium gives print images having excellent scratch or abrasion resistance without any deterioration in clearness of print image. The recording medium of self-correctable type gives print images which can be corrected clearly by a self-correction method.
