Benefits of technology

This patented technology allows for an improved colored liquid that combines two types of liquids together - one made from natural colors like red or yellow (dyes) while another uses other chemicals such as acacia gum, guar glue, talc powder, etc., along with various ingredients like humectants, preservatives, solvents, stabilizers, antioxidants, lubricity agents, antiwears/rustings agents, and others. These compositions can be used alone without any further mixing steps before being applied on paper products.

Problems solved by technology

This patented technical issue addressed in this patent relates to finding an ideal method or composition that allows for producing both strong and durable colored liquid ink used for printing purposes while addressing issues like insufficient water resistivity and ease of manufacturing due to its use of specific types of chemical substances called dyers.
