Problems solved by technology

As cleaning agents for pigment-dispersed photosensitive resin compositions, for example, the cleaning agents described in Patent Documents 1 and 2 are known, but these known cleaning compositions do not have the performance to satisfy all the above-mentioned required properties.
[0007] In addition, the foaming properties of conventional cleaning agents containing cationic, anionic, and nonionic surfactants have become a problem. In order to obtain sufficient cleaning effects, a large amount of new cleaning agents must be used, and the amount of waste liquid treatment has increased. Large, so there is a problem of large environmental load

Abstract

The invention provides a detergent, useful for removal of pigment-dispersive photosensitive resin. Compared with previous products, the detergent of the invention develops cleaning effect with less amount and is difficult to arouse aggregation and sinking of detergent. The said detergent is characteristic in that it contains more than two of aromatic compounds having at least one alkyl, wherin the total number of carbon atoms of all alkyl groups is 3-5.

Description

technical field [0001] The present invention relates to a cleaning agent for a photosensitive resin composition. Background technique [0002] Conventionally, as a cleaning agent for resin compositions for semiconductors, for example, OK-73 (manufactured by Tokyo Ohka Industry Co., Ltd.; trade name) and the like have been used, and when it is used for cleaning pigment-dispersed photosensitive resin compositions, especially carbon black , there is a problem of generation of foreign matter due to aggregation-sedimentation of the pigment, and thus it is not suitable. [0003] In addition, if an aprotic polar solvent with a high boiling point is used alone, its polarity is too strong to cause aggregation and sedimentation of the pigment, causing inconveniences such as pipe clogging. [0004] Furthermore, even when an aromatic hydrocarbon compound is used alone, pigment aggregation-sedimentation occurs, and an efficient cleaning effect cannot be obtained. [0005] As a resin re...
