PROTECTIVE AGENT AND APPLICATION METHOD THEREOF, LOW TEMPERATURE TRANSPIRING COMPOSITION AND TREATMENT AGENT OF METAL PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide an application method of a protective agent capable of transpiring a decomposition product of acid degradable polymer at low temperature.SOLUTION: Steam pressure of a decomposition product can be reduced by using an acid degradable polymer having a repeating unit represented by the following formula (1) as a protective agent and decomposing the acid degradable polymer with an acidic compound having pK4 or less. In the formula (1), Arepresents a hydrocarbon group which may have a substituent or a -A-(O-A)- group, where Aand Aare same or different and each represent a hydrocarbon group which may have a substituent, and n is an integer of 1 or more.SELECTED DRAWING: None
