Abstract
The present disclosure is drawn to polymeric amine synergists, photo curable inks containing the polymeric amine synergists, and methods of making the photo curable inks. A polymeric amine synergist can include an aminobenzene modified with a polyether chain connecting to the aminobenzene through an amide linkage.
Claims13
A polymeric amine synergist having formula:
- wherein m, n, and p are independently any integer provided that the sum of m, n, and p is from 10 to 25 and that m or p is at least 1, and wherein the polymeric amine synergist has a molecular weight from about 500 Mw to about 5000 Mw.
A photo curable ink, comprising:
- a photo reactive binder;
- a polymeric amine synergist comprising an aminobenzene modified with a polyether chain connecting to the aminobenzene through an amide linkage such that the polyether chain is directly bonded to a nitrogen atom of the amide group, wherein the polyether chain comprises a copolymer of polyethylene glycol and polypropylene glycol;
- a type-II photo initiator;
- a colorant;
- and
- a liquid vehicle including co-solvent and water.
A method of making a photo curable ink, comprising mixing a photo reactive binder, a polymeric amine synergist comprising an aminobenzene modified with a polyether chain connecting to the aminobenzene through an amide linkage such that the polyether chain is directly bonded to a nitrogen atom of the amide group, wherein the polyether chain comprises a copolymer of polyethylene glycol and polypropylene glycol, a type-II photo initiator, a colorant, and a liquid vehicle including co-solvent and water.
