    • In a composition containing a photothermal conversion material, which is suitable for use in a method of perforating a heat-sensitive stencil sheet by ejecting a photothermal conversion material contained in a liquid from a liquid-ejecting means to transfer it together with said liquid onto a heat-sensitive stencil sheet, and then exposing said heat-sensitive stencil sheet to a visible or infrared ray to allow the photothermal conversion material to emit heat so that said heat-sensitive stencil sheet is perforated specifically at portions to which said photothermal conversion material has been transferred, the perforation can be efficiently performed by use of a liquid containing a photothermal conversion material by appropriately selecting boiling point and heat of vaporization of a major component of the liquid.A composition for perforating a heat-sensitive stencil sheet containing a photothermal conversion material in a liquid, said liquid comprising a solvent having a boiling point of 50 to 250.degree. C. and a heat of vaporization of 200 cal/g or less in an amount of at least 50% by weight based on the total of said liquid. Said photothermal conversion material is preferably carbon black in an amount of 0.1 to 30% by weight of the composition.

    • A heat-sensitive stencil sheet, and a method and a composition for perforating the same are provided, in which photothermal conversion materials transferred to the stencil sheet do not blur or spread but are fixed thereon faithfully to desired images, and clear images are printed. The heat-sensitive stencil sheet has on a side thereof a liquid absorbing layer to which the photothermal conversion material is to be transferred, and the liquid absorbing layer comprises a hydrophilic resin and a water-repellent compound, and optionally organic and/or inorganic particulates. The hydrophilic resin and the water-repellent compound may be mixed at a proportion sufficient to provide a contact angle of 20 to 150 degrees between the liquid absorbing layer and the liquid. The liquid, in which the photothermal conversion material is contained, can comprise water and/or a hydrophilic solvent. The liquid absorbing layer preferably has a softening or melting point of 40 to 120.degree. C. and has a thickness of 0.01 to 20 .mu.m.
    • 提供一种热敏蜡纸,以及用于对其进行穿孔的方法和组合物,其中转印到蜡纸上的光热转换材料不会模糊或扩散,而是将其忠实地固定在所需的图像上,并且打印清晰的图像。 热敏蜡纸在其侧面上具有要转移光热转换材料的液体吸收层,并且液体吸收层包含亲水性树脂和拒水性化合物,以及任选的有机和/或无机颗粒 。 亲水性树脂和防水化合物可以以足以在液体吸收层和液体之间提供20至150度的接触角的比例混合。 含有光热转换材料的液体可以包含水和/或亲水性溶剂。 液体吸收层的软化点或熔点优选为40〜120℃,厚度为0.01〜20μm。
