Patent ID: 11938734

Abstract:
A cleaning solution containing a compound represented by formula (1), a compound represented by formula (2), and water; and an inkjet printer cleaning method using the same. R1—O(EO)m(PO)nH  (1)R2—O(EO)LH  (2)In formula (1), R1 represents a linear or branched C1-C30 alkyl group. EO represents an ethyleneoxy group, and PO represents a propyleneoxy group. m and n each independently represent an integer of 1-5. m:n, which is the ratio between m and n, is at least 1:2 and smaller than 3:2. In formula (2), R2 represents a linear or branched C1-C30 alkyl group, or an aryl group. EO represents an ethyleneoxy group. L represents an integer of at least 10. Formula (1): R1—O(EO)m(PO)nH. Formula (2): R2—O(EO)LH.
