Definitions

  • the present invention relates to a heat mode recording material for making a lithographic plate for use in lithographic printing.
  • the present invention further relates to a method for imaging said heat mode recording material e.g. by means of a laser.
  • Lithographic printing is the process of printing from specially prepared surfaces, some areas of which are capable of accepting ink (hydrophobic areas) whereas other areas will not accept ink (hydrophilic areas).
  • hydrophobic areas some areas of which are capable of accepting ink
  • hydrophilic areas other areas will not accept ink (hydrophilic areas).
  • both water or an aqueous dampening liquid and ink are applied to the plate surface that contains hydrophilic and hydrophobic areas.
  • the hydrophilic areas will be soaked with water or the dampening liquid and are thereby rendered oleophobic while the hydrophobic areas will accept the ink.
  • DE-A-2448325 discloses a laser heat mode "direct negative" printing plate comprising e.g. a polyester film support provided with a hydrophilic surface layer.
  • the disclosed heat mode recording material is imaged using an Argon laser thereby rendering the exposed areas hydrophobic.
  • An offset printing plate is thus obtained which can be used on an printing press without further processing.
  • the plate is called a "direct negative” plate because the areas of the recording material that have been exposed are rendered ink accepting.
  • Laser exposure renders the exposed areas insoluble and ink receptive, whereas the non exposed image portions remain hydrophilic and water soluble allowing to be removed by the dampening liquid during printing exposing the hydrophilic support.
  • Such plates can be used directly on the press without processing.
  • DD-A-155407 discloses a laser heat mode "direct negative" printing plate where a hydrophilic aluminum oxide layer is rendered oleophilic by direct laser heat mode imaging. These printing plates may also be used on the press without further processing.
  • this lithographic printing plate of high quality preferably can be obtained by development under essential dry conditions or with plain water or by using the imaged non processed plate directly on the press, these processing methods are referred to as 'ecological processing'.
  • a heat mode recording material comprising on a support having a ink receptive surface or being coated with an ink receptive layer a substance capable of converting light into heat and a hardened hydrophilic surface layer having a thickness not more than 3 ⁇ m.
  • a method for making a lithographic printing plate comprising the steps of:
  • the thickness of the hydrophilic surface layer is not more than 3 ⁇ m preferably not more than 1 ⁇ m.
  • the minimum thickness of the surface layer is not particularly critical but is preferably more than 0.05 ⁇ m.
  • a particularly interesting range for the thickness of the hydrophilic surface layer is between 0.05 ⁇ m and 0.5 ⁇ m.
  • the heat mode recording material is image-wise exposed using a laser.
  • lasers are e.g. semiconductor lasers, YAG lasers e.g. Nd-YAG lasers, Argon lasers, ect..
  • the laser may have a power output between 40 mW and 10000 mW and preferably operates in the infrared part of the spectrum.
  • the hydrophilic surface layer is removed at the exposed imaged areas.
  • Removing can be done by e.g. rubbing using e.g. a brush or a cotton pad. Such rubbing may be carried out during image-wise exposure as described in US-P-5.148.746. Rubbing of the heat mode recording material is preferably carried out in absence of a liquid in essentially dry conditions. However plain water or a water based developer may be used also.
  • Removing the hydrophilic surface layer on the imaged areas can further be done by ultrasonic treatment of the imaged recording material immersed in plain water or a water based developer, by means of a pressure jet of plain water or a water based developer. Removal of the exposed areas may also be done by directly mounting the plate on a printing machine so that the dampening liquid dissolves and removes the hydrophilic surface layer at the exposed areas during startup of the printing machine.
  • the substance capable of converting light into heat may be present in the support and/or in a separate recording layer provided between the support and the hardened hydrophilic surface layer.
  • the thickness of such a separate recording layer may be varied over a wide range. However when the thickness of such recording layer becomes more than 3 ⁇ m image-wise exposure should then be carried out through the hardened hydrophilic surface layer. In this case it also preferred not to include an additional layer between such recording layer and the hardened hydrophilic surface layer or to keep the thickness of such additional layer to a minimum preferably not more than 0.5 ⁇ m. Furthermore when using a recording layer having a thickness of more than 3 ⁇ m such layer should then be ink receptive.
  • the thickness of the recording layer is less than 3 ⁇ m exposure can take place through the support, when transparent, or through the hardened hydrophilic layer.
  • the recording layer will generaly not be required to be ink receptive as long as the underlying surface or layer is ink receptive and total removal of the recording layer together with the hydrophilic surface layer at the exposed areas is possible.
  • a recording layer is used having a thickness between 0.01 ⁇ m and 30 ⁇ m.
  • Examples of substances capable of converting light into heat are e.g. carbon black, infrared or near infrared absorbing dyes or pigments, metals such as Bi, Sn, Te etc. or a combination thereof.
  • Suitable infrared dyes are disclosed in e.g. US-4833124, EP-321923, US-4774583, US-4942141, US-4948776, US-4948777, US-4948778, US-4950639, US-4950640, US-4912083, US-4958552, US-5024990, US-5023229 etc.
  • Suitable infrared pigments are e.g. HEUCODOR metal oxide pigments available from Heubach Langelsheim.
  • the recording layer is preferably a vacuum or vapour deposited metal layer.
  • the recording layer may be a vacuum deposited aluminium layer.
  • the thickness of such an aluminium layer however should be less than 250 ⁇ and more preferably between 100 ⁇ and 225 ⁇ .
  • Polymeric binders for the recording layer are preferably hydrophobic such as e.g. cellulose esters e.g. cellulose acetate, cellulose nitrate, a copolymer of vinylidene chloride and acrylonitrile, poly(meth)acrylates, polyvinyl chloride, etc..
  • the polymeric binder in the recording layer is heat sensitive: e.g. a polymer containing nitrate ester groups (e.g. self oxidizing binder cellulose nitrate as disclosed in GB-1316398 and DE-A-2512038); e.g. a polymer containing carbonate groups (e.g. polyalkylene carbonate); e.g. a polymer containing covalently bound chlorine (e.g. polyvinylidene chloride).
  • Suitable supports for a heat mode recording material used in connection with the present invention are preferably non-metallic supports having a hydrophobic (ink receptive) surface e.g. a polyester film support, paper coated with a polyolefin such as polyethylene, polycarbonate film, polystyrene film etc..
  • metallic support such as e.g. aluminium can also used in connection with the present invention.
  • the surface of the support is not or insufficiently hydrophobic it may be provided with an intermediate hydrophobic primer coating whereon a recording layer may be deposited.
  • the recording layer can be the hydrophobic layer at the same time.
  • the recording layer may comprise additional substances such as plasticizers, crosslinking agents and resins, particulate materials such as e.g. polyethylene or fluorinated polymer dispersions, etc.. to impart toughness, print durability and oleophilic surface characteristics of the ablated image portions of the recording layer, wetting agents, matting agents, anti-oxidizing agents etc..
  • the recording layer will be hardened when it includes a binder.
  • any polymeric binder is suitable provided the adherance between the recording layer and the support is thereby improved. It has also been found that when the undercoat layer contains a polymer with heat labile groups (e.g. covalently bound chloride) adjacent to the recording layer the speed of the recording material can be improved as disclosed in EP 573091
  • imaging of the heat mode recording material takes place through the hydrophilic surface layer.
  • excellent image quality high sharpness, good contrast, excellent resolution
  • increased sensitivity are obtained.
  • hydrophilic coatings are preferably cast from aqueous compositions containing hydrophilic binders having free reactive groups including e.g. hydroxyl, carboxyl, hydroxyethyl, hydroxy-propyl, amino, aminoethyl, aminopropyl, carboxymethyl, etc.. along with suitable crosslinking or modifying agents including e.g. hydrophilic organotitanium reagents, aluminoformyl acetate, dimethylol urea, melamines, aldehydes, hydrolyzed tetraalkyl orthosilicate, etc..
  • hydrophilic organotitanium reagents e.g. hydrophilic organotitanium reagents, aluminoformyl acetate, dimethylol urea, melamines, aldehydes, hydrolyzed tetraalkyl orthosilicate, etc.
  • Suitable polymers for hydrophilic layers may be selected from the group consisting of gum arabic, casein, gelatin, starch derivatives, carboxymethyl cellulose and Na salt thereof, cellulose acetate, sodium alginate, vinyl acetate-maleic acid copolymers, styrene-maleic acid copolymers, polyacrylic acids and salts thereof, polymethacrylic acids and salts thereof, hydroxy-ethylene polymers, polyethylene glycols, hydroxypropylene polymers, polyvinyl alcohols, and hydrolyzed polyvinylacetate having a hydrolyzation degree of at least 60% by weight and more preferably at least 80% by weight.
  • Hydrophilic layers containing polyvinylalcohol or polyvinylacetate hydrolyzed to an extent of at least 60% by weight hardened with a tetraalkyl orthosilicate, e.g. tetraethyl orthosilicate or tetramethyl orthosilicate, as disclosed in e.g. US-P-3476937 are particularly preferred because their use in the present heat mode recording material results in excellent lithographic printing properties.
  • a further suitable hardened hydrophilic surface layer is disclosed in EP 514990
  • the hydrophilic layer disclosed in this EP-application comprises the hardening reaction product of a (co)polymer containing amine or amide functions having at least one free hydrogen (e.g. amino modified dextrane) and aldehyde.
  • the hardened hydrophilic surface layer may comprise additional substances such as e.g. plasticizers, pigments, dyes etc..
  • the hardened hydrophilic surface layer may also comprise particulate materials such as e.g. TiO 2 or colloidal silica to increase the strength and/or hydrophilic character of the hydrophilic layer.
