Fabric printable medium

A method for forming a fabric printable medium, comprising:

• applying an ink receiving composition including:
• a first crosslinked polymeric network;
• a second crosslinked polymeric network;
• a flame retardant agent;
• and
• a physical networking agent selected from the group consisting of an acrylate copolymer, a polyacrylic acid copolymer, a polyester copolymer, a polyurethane copolymer, and combinations thereof, the physical networking agent having a weight average molecular weight ranging from 300,000 Mw to 1,000,000 Mw to an image-side of a fabric base substrate, thereby forming a flame retardant ink receiving layer on the image-side of the fabric base substrate;
• and
• applying a waterproofing composition to a back-side of the fabric base substrate, thereby forming a waterproof coating on the back-side of the fabric base substrate.

A printing method, comprising:

• obtaining a fabric printable medium including:
• a fabric base substrate having an image-side and a back-side;
• a flame retardant ink receiving layer on the image-side of the fabric base substrate, the flame retardant ink receiving layer including:
• a first crosslinked polymeric network;
• a second crosslinked polymeric network;
• a flame retardant agent;
• and
• a physical networking agent selected from the group consisting of an acrylate copolymer, a polyacrylic acid copolymer, a polyester copolymer, a polyurethane copolymer, and combinations thereof, the physical networking agent having a weight average molecular weight ranging from 300,000 Mw to 1,000,000 Mw;
• and
• a waterproof coating on the back-side of the fabric base substrate;
• and
• applying an ink composition onto the flame retardant ink receiving layer to form a printed image.
