Title:
ANTISTATIC AGENT
Document Type and Number:
WIPO Patent Application WO/2023/281771
Kind Code:
A1
Abstract:
An antistatic agent (Z) which comprises a block polymer (A) comprising a block of a hydrophobic polymer (a) and a block of a hydrophilic polymer (b) as constituent units and sulfonic acid salts (S), wherein the sulfonic acid salts (S) include at least two alkylbenzenesulfonic acid salts which are salts each constituted from an alkylbenzenesulfonic acid anion (the alkyl having 6-18 carbon atoms) and which differ in the number of carbon atoms of the alkyl group of the anion, the sulfonic acid salts (S) satisfying the relationship 0.40≤W(n)/[W(n-1)+W(n)+W(n+1)]≤0.90 (wherein n is the number of carbon atoms of the alkyl group of the anion as a component of an alkylbenzenesulfonic acid salt having the highest weight proportion of the sulfonic acid salts (S); W(n) is the weight of said alkylbenzenesulfonic acid salt; and W(n-1) and W(n+1) are the weights of alkylbenzenesulfonic acid salts respectively including an anion having an alkyl group with n-1 carbon atoms and an anion having an alkyl group with n+1 carbon atoms).
