Abstract
Printable compositions comprising a liquid carrier; and a radiation curable polyurethane dispersed in the liquid carrier are described, as well as methods of preparing the printable compositions and methods of printing using the printable compositions.
Claims20
A printable composition, comprising:
- a liquid carrier;
- and
- a radiation curable polyurethane dispersed in the liquid carrier, the curable polyurethane formed from:
- a polyisocyanate;
- a (meth)acrylate-containing polyol including a diglycidyl ester;
- a mono-alcohol having (meth)acrylate functionality;
- and
- an amino acid, wherein the amino acid comprises one or more of, valine, glutamine, asparagine, glutamic acid, phenylalanine, and proline.

A method of preparing a printable composition, comprising:
- reacting a polyisocyanate and a (meth)acrylate-containing polyol to form a polyurethane pre-polymer, wherein the (meth)acrylate-containing polyol includes a diglycidyl ester;
- reacting the polyurethane pre-polymer with a mono-alcohol having (meth)acrylate functionality to form a functionalised polyurethane pre-polymer;
- and
- reacting the functionalised polyurethane pre-polymer with an amino acid to form a radiation curable polyurethane, wherein the amino acid comprises one or more of, valine, glutamine, asparagine, glutamic acid, phenylalanine, and proline;
- and
- dispersing the radiation curable polyurethane in a liquid carrier.
3 more elements
A method of printing, comprising:
- printing a composition comprising:
- a liquid carrier;
- and
- a radiation curable polyurethane dispersed in the liquid carrier, the curable polyurethane formed from:
- a polyisocyanate;
- a (meth)acrylate-containing polyol, wherein the (meth)acrylate-containing polyol includes a diglycidyl ester;
- a mono-alcohol having (meth)acrylate functionality;
- and
- an amino acid, wherein the amino acid comprises one or more of valine, glutamine, asparagine, glutamic acid, phenylalanine, and proline;
- and
- irradiating the printed composition.
