Definitions

  • a substituted or unsubstituted aralkyl group is preferably a phenyl or naphthyl group including one, two, three or more C 1 to C 6 -alkyl groups.
  • substituted in e.g. substituted alkyl group means that the alkyl group may be substituted by other atoms than the atoms normally present in such a group, i.e. carbon and hydrogen.
  • a substituted alkyl group may include a halogen atom or a thiol group.
  • An unsubstituted alkyl group contains only carbon and hydrogen atoms
  • compositions may also be provided onto a support by any printing method such as intaglio printing, screen printing, flexographic printing, offset printing, inkjet printing, valve jet printing, rotogravure printing, etc.
  • a printing method is preferred when only a part or several parts of a support has to be provided with the colour-forming layers.
  • a preferred aqueous based composition includes encapsulated leuco dyes.
  • leuco dyes are disclosed in for example EP-A 3297837 , EP-A 3470134 and EP-A 3470135 , all from Agfa Gevaert NV.
  • IR pigment is carbon black, such as acetylene black, channel black, furnace black, lamp black, and thermal black.
  • acid scavengers may improve the storage stability of the laser markable article.
  • UV-absorbers examples include 2-hydroxyphenyl-benzophenones (BP) such as Chimassorb TM 81 and Chimassorb TM 90 from BASF; 2-(2-hydroxyphenyl)-benzotriazoles (BTZ) such as Tinuvin TM 109, Tinuvin TM 1130, Tinuvin TM 171, Tinuvin TM 326, Tinuvin TM 328, Tinuvin TM 384-2, Tinuvin TM 99-2, Tinuvin TM 900, Tinuvin TM 928, Tinuvin TM Carboprotect TM Tinuvin TM 360, Tinuvin TM 1130, Tinuvin TM 327, Tinuvin TM 350, Tinuvin TM 234 from BASF, Mixxim TM BB/100 from FAIRMOUNT, Chiguard 5530 from Chitec; 2-hydroxy-phenyl-s-triazines (HPT) such as Tinuvin TM 460, Tinuvin TM 400, Tinuvin TM 405, Tinuvin
  • a preferred co-initiator is selected from the group consisting of an aliphatic amine, an aromatic amine and a thiol. Tertiary amines, heterocyclic thiols and 4-dialkylamino-benzoic acid are particularly preferred as co-initiator.
  • An interlayer maybe provided between the colour-forming layers.
  • the interlayer preferably contains an acid scavenger as described above to prevent diffusion of an acid from one laser markable layer to another.
  • compositions may be applied on any type of support, for example a metallic support, a glass support, a polymeric support, or a paper support.
  • the compositions may also be applied on a textile surface.
  • paper there is no real limitation on the type of paper and it includes newsprint paper, magazine paper, office paper, or wallpaper but also paper of higher grammage, usually referred to as paper boards, such as white lined chipboard, corrugated (fiber) board and packaging board.
  • paper boards such as white lined chipboard, corrugated (fiber) board and packaging board.
  • BOPET foils and supports are well-known in the art of preparing suitable supports for silver halide photographic films.
  • GB 811066 (ICI) teaches a process to produce biaxially oriented polyethylene terephthalate foils and supports.
  • Marking is preferably carried out in-line in the packaging process.
  • An advantage of laser or thermal printing marking is the possibility to add data at a very late stage of the packaging process.
  • the transparent support may include UV absorbers to act as a UV blocking layer.
  • a UV blocking layer may also be provided on either side of the support.
  • any laser may be used.
  • the laser is preferably an infrared (IR) laser.
  • Raster and vector are different graphic file types which require different modes of laser processing.
  • the main difference between vector and raster graphics is that raster graphics are composed of pixels, while vector graphics are composed of paths or lines.
  • Heat may be applied to the heat-sensitive article by means of a so-called thermal print heads.
  • the number of heating elements of a print head determines the print resolution. Typical values are 200 to 300 heating elements (dots) per inch (dpi). However, thermal printers with a resolution of 400 and 600 dpi are also available.
  • IR1064 is an infrared absorbing dye with the following structure, IR1064 can be prepared according to the synthetic methods reported in EP-A 2463109 (Agfa), paragraphs [0150] to [0159].
  • Ethyl Maleate is commercially available from TCI Europe.
  • Inimix is a 1/1/1/ mixture of Genocure DMHA, Genocure CPK and Genocure TPO.
  • Desmolux XP 2587 is an aliphatic urethane acrylate commercially available from Allnex.
  • a coating composition SUB-1 was prepared by mixing the components according to Table 1 using a dissolver. Table 1 wt% of components SUB-1 deionized water 76.66 CCE 18.45 Resorcinol 0.98 PAR-sol 0.57 PEA-sol 0.68 DOW-sol 1.33 Surfynsol 1.33
