Document Type and Number:
Japanese Patent JP3807492
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a composition for an ink-absorbing agent, having a low contact angle and dynamic surface tension immediately after dropping, and having an excellent ink absorption.
SOLUTION: The composition for the ink-absorbing agent is composed of (A) one or more kinds of 5-80 wt.%, selected from ethoxylated compounds of acetylene glycol shown by formula (1) (R1 and R2 are each an alkyl group) and an acetylene glycol shown by formula (2) (R1 and R2 are each an alkyl group; m and n are each a positive number; and m+n is 10 or below), and (B) one or more kinds of 20-95 wt.% of ethoxylated compounds of acetylene glycol shown by formula (3) (R3 and R4 are each an alkyl group, p and q are each a positive number, and p+q is 10-40), having an HLB of 10-18, wherein the contact angle is 70 degrees or below and the dynamic surface tension at 1 Hz and 10 Hz is 50 mN/m or below after 30 sec from the time when a 0.1 wt.% aqueous solution of the composition is dropped.
