摘要： Cresol-formaldehyde novolak resins made from a mixture containing meta- and paracresol or ortho-, meta- and paracresol in a ratio selected from a given range for use in fast positive photoresist compositions together with one or more sensitizing compounds. When dissolved in a mixture of organic solvents, the photoresist compositions are suitable for application as a thin coating to a substrate. After the coating has been dried, the coated substrate can be exposed to image-wise modulated actinic radiation and developed in alkaline solution, yielding a relief pattern of resist on substrate useful for a number of applications.
摘要翻译：甲磺醛酚醛清漆树脂由含有间 - 和对甲酚或邻 - 间 - 和对羟基苯甲酸酯的混合物制成，其比例选自用于快速正性光致抗蚀剂组合物与一种或多种增感化合物的给定范围。当溶解在有机溶剂的混合物中时，光致抗蚀剂组合物适合作为薄涂层施用于基底。在涂层干燥后，涂覆的基底可以暴露于成像调制的光化辐射并在碱性溶液中显影，产生可用于多种应用的底物上的抗蚀剂的浮雕图案。

摘要： A hybrid liquid toner composed of a mixture of two different types of liquid toner. One type is a liquid toner that includes a complex amphipathic molecule of which at least a fixer and a dispersant are polymeric moieties and which additionally includes a charge director and optionally includes a color agent, all of these being carried by a volatile organic solvent of high electrical resistivity. The other type of liquid toner is one that includes a fixer and a dispersant as separate chemical entities and further includes a charge director, a pigment type color agent and a carrier solvent such as mentioned above. The two toners can be mixed in a very wide range of proportions and when so mixed have several advantages which makes the hybrid toner particularly useful in connection with preparation of lithographic masters and microfiche reproductions by electrostatography as well as useful as an all purpose liquid toner.
摘要翻译：由两种不同类型的液体调色剂的混合物组成的混合液体调色剂。一种类型是液体调色剂，其包括复合两亲分子，其至少定影剂和分散剂是聚合物部分，并且另外包含电荷导向剂，并且任选地包含着色剂，所有这些都由高的挥发性有机溶剂携带电阻率。另一种类型的液体调色剂是包括固定剂和分散剂作为单独化学实体的另一种类型，并且还包括电荷导向剂，颜料型着色剂和如上所述的载体溶剂。两种调色剂可以以非常宽的比例混合，并且当混合时具有几个优点，这使得混合调色剂在通过静电摄影制备平版印刷母版和缩微胶片复制物方面特别有用，并且作为全能液体调色剂是有用的。
