Flushing agent and method of manufacturing the linked material

Abstract

The invention of a fluxing agent that can be used in a suitable manner for application in printing plates with high wettability and high void-blocking capability, even when bonding is performed at relatively low temperatures. The flux consists of rosin, an organic acid, and a solvent (S) used. The organic acid consists of a monocaiboxyl acid (Al) with a melting point of 35°C or higher and 90°C or lower, and the solvent (S) consists of a solvent (Si) with a boiling point of 10°C or lower. The invention also proposes a method for producing the bonded material.
