Abstract
An ink composition for inkjet recording comprising water and a compound represented by the following Structure: wherein at least one of Z1, Z2, Z3, and Z4 are not hydrogen; each of R1, R2 and R3 are independently selected from the group consisting of hydrogen and methyl, R4 is —H, —CH3, —C2H5, or —C3H7, or —CH2O(CH2CHR5O)x4Z4, wherein each R5 is independently hydrogen or methyl; b is 0 or 1; x1, x2, x3, and x4 are each equal to at least 1, the sum of x1, x2, x3 is 3 to 45 when R4 is not —CH2O(CH2CHR5O)x4Z4, and the sum x1, x2, x3, and x4 is from 3 to 60 when R4 is —CH2O(CH2CHR5O)x4Z4. Such compounds have been found to provide improved curl control.
