(c) a binder. The invention also provides alternative ink formulations for laser marking, a method of forming an image using the ink formulations and a substrate coated with the ink formulation of the invention. Ink formulations according to the invention have been found to have good laser imaging efficacy, and an essentially negligible impact on the background colour of the coating.</description><language>eng ; fre ; ger</language><subject>ADHESIVES ; CHEMICAL PAINT OR INK REMOVERS ; CHEMISTRY ; CINEMATOGRAPHY ; COATING COMPOSITIONS, e.g. PAINTS, VARNISHES ORLACQUERS ; COLOUR PRINTING ; CORRECTING FLUIDS ; CORRECTION OF TYPOGRAPHICAL ERRORS ; DYES ; ELECTROGRAPHY ; ELECTROPHOTOGRAPHY ; FILLING PASTES ; HOLOGRAPHY ; i.e. MECHANISMS PRINTING OTHERWISE THAN FROM A FORME ; INKS ; LINING MACHINES ; MAGNETOGRAPHY ; METALLURGY ; MISCELLANEOUS APPLICATIONS OF MATERIALS ; MISCELLANEOUS COMPOSITIONS ; NATURAL RESINS ; PAINTS ; PASTES OR SOLIDS FOR COLOURING OR PRINTING ; PERFORMING OPERATIONS ; PHOTOGRAPHY ; PHYSICS ; POLISHES ; PRINTING ; PRINTING, DUPLICATING, MARKING, OR COPYING PROCESSES ; SELECTIVE PRINTING MECHANISMS ; STAMPS ; TRANSPORTING ; TYPEWRITERS ; USE OF MATERIALS THEREFOR ; WOODSTAINS</subject><creationdate>2020</creationdate><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20200129&DB=EPODOC&CC=EP&NR=3401372B1$$EHTML$$P50$$Gepo$$Hfree_for_read</linktohtml><link.rule.ids>230,308,776,881,25542,76289</link.rule.ids><linktorsrc>$$Uhttps://worldwide.espacenet.com/publicationDetails/biblio?FT=D&date=20200129&DB=EPODOC&CC=EP&NR=3401372B1$$EView_record_in_European_Patent_Office$$FView_record_in_$$GEuropean_Patent_Office$$Hfree_for_read</linktorsrc></links><search><creatorcontrib>JARVIS, Anthony</creatorcontrib><title>INK FOR LASER IMAGING</title><description>In a first aspect, the invention provides an ink formulation comprising:
