Abstract

Biodegradable ink composition for ink jet printing, liquid at room temperature, comprising: a) a binder comprising at least 0.5% by weight relative to the total weight of the ink, of at least one biodegradable polymer having a weight average molecular weight less than 70 kDa, preferably less than 60 kDa, more preferably less than 50 kDa, further preferably less than 40 kDa, expressed as polystyrene equivalents; b) an organic vehicle or solvent comprising, preferably composed of, one or more organic solvent compound (s), and optionally water; c) at least 0.1% by weight relative to the total weight of the ink of one or more dye(s) and / or pigment (s); wherein the biodegradable polymer is chosen from among polyhydroxyalkanoates (PHA), polyesteramides (PEA), poly (glycolic acid) s, poly (lactic acid) s (PLA), polycaprolactones (PCL), the copolymers thereof; and aliphatic copolyesters such as succinates, adipates and terephtalates; and wherein the ink composition has a viscosity of 1 to 20 mPa.s, preferably of 2 to 10 mPa.s at 20°C. Process for marking a substrate using said ink composition. Substrate provided with marking obtained by drying and / or absorption of said ink composition.

Description

technical field [0001] The present invention relates to liquid ink compositions for marking all types of supports, substrates and objects, the properties of which are particularly suitable for inkjet marking or Print a wide variety of supports, substrates and objects, whether they are porous or non-porous. The ink composition of the invention is defined as a biodegradable ink composition, and preferably the ink composition of the invention is additionally also a compostable ink composition. Background technique [0002] Biodegradable compositions, components, components, components generally refer to such compositions, components, components, components that can be degraded, decomposed preferably rapidly by living organisms such as microorganisms without polluting the natural environment. [0003] Biodegradation is explained as the progressive simplification of the chemical structure of organic compounds containing inter alia carbon, hydrogen, oxygen, nitrogen atoms, accomp...
