Document Type and Number:
WIPO Patent Application WO/2024/080204
Kind Code:
A1
Abstract:
The present invention provides a cleaning agent which exhibits high cleaning power against a paste adhered to a screen-printing plate, inhibits the effect of an emulsion on a screen-printing plate, has a uniform appearance, and contains water as a primary component. The present invention is a cleaning agent composition that contains: 0.5-10 mass% of a component (A); 1-10 mass% of a component (B); 1-10 mass% of a component (C); 0.1-5 mass% of a component (D); and 65.0-97.4 mass% of water. Component (A): a compound which has an alicyclic hydrocarbon group or an aromatic hydrocarbon group and has a molecular weight of 90-180. Component (B): a compound represented by formula (1). Component (C): a compound represented by formula (2). Component (D): a surfactant having an aromatic group (the average number of added moles of C2H4O groups is 20-100). Formula (2): R1-O-(C2H4O)n-H. (R1 denotes a branched alkyl group having 6-18 carbon atoms, and the value of n, which is the average number of added moles of C2H4O groups, is 2-12).
