Abstract
A method of printing a polyamide structure using two or more of water-soluble dye with an inorganicity/organicity value of 1 to 7 selected so that the ones with the largest and smallest inorganicity/organicity values show a difference of 2 or below between their two such values, to allow the polyamide structure to be printed with no uneven color, high color reproducibility and excellent ink bleeding prevention.
Claims19
A method of printing a polyamide structure, which comprises applying two or more types of water-soluble dyes with an inorganicity/organicity value of 1 to 7 selected so that the ones with the largest and smallest inorganicity/organicity values show a difference of 2 or below between their two such values and at least one of these dyes has an inorganicity/organicity value of 3.2 or more.
An inkset for inkjet printing of a polyamide structure, consisting of two or more inks containing water-soluble dyes and a wetting agent, wherein said water-soluble dyes range in their inorganicity/organicity values from 1 to 7, of which the ones with the largest and smallest inorganicity/organicity values show a difference of 2 or below between their two such values and at least one of these dyes has an inorganicity/organicity value of 3.2 or more.
