Abstract
The present invention relates to a heat-sensitive composition and its use, comprising: a phenolic resin; (b) a dissolution inhibitor; (c) a compound having infrared radiation absorbing properties; and (d) a solvent resistance additive. The heat-sensitive composition of the present invention can be used in thermal offset printing, has good solvent resistance, can improve the process speed and increase the print resistance of a printing plate, and exhibits excellent developability and alkali resistance.
Description
Technical field
The present invention relates to a kind of heat-sensitive composition, refer to a kind of method that can be used for the thermal sensitivity coating composition in the temperature-sensitive hectographic printing and use said heat-sensitive composition shop drawings picture especially.
Background technology
Known printing technology mainly is divided into four big class methods: intaglio printing, letterpress, serigraphy and hectographic printing.
Above-mentioned hectographic printing is a kind of indirect printing.The blanket of going up behind the printing ink again via an intermediary through roller coating (blanket) is transferred on the substrate, promptly like surfaces such as paper, clothes.And principle of China ink is to utilize the immiscible principle of profit on it; Make the oleophylic district have different affinity to printing ink with hydrophilic area; When applying printing ink (ink), non-image district attracted water and repel printing ink, image area (image area) is accepted printing ink and is repelled water simultaneously.
Two kinds of common main method of hectographic printing are: PS version (pre-coating light sensitive plate (presensitized plate)) printing and CTP version (CTP (computer to plate)) printing.If utilizing a film or the selectivity of photoresist to make public, PS edition owner reaches the purpose of shop drawings picture; Its shortcoming be film or photoresist manufacturing and gold-tinted chamber use (PS often is light source with ultraviolet light) and the technical matters that needs manual synchronizing.
Recently use the CTP version to replace the traditional PS version; The CTP version is because through the computer control thermal source; Therefore do not need the action of manual synchronizing forme and need not to use the gold-tinted chamber, can be in general indoor plate-making, and also plate-making efficient, output speed and seal amount are compared all comparatively excellent with the PS version.
CTP technology need be used the thermal sensitivity coating composition, and it can be divided into two big types, i.e. positive-working, thermally sensitive based coating composition and minus thermal sensitivity coating composition.Positive-working, thermally sensitive based coating composition:, can be dissolved in developer solution at heated portion; Heat affected zone is not then dissolved.Resolution is better than minus thermal sensitivity coating composition, and therefore most offset print technology uses the positive-working, thermally sensitive based coating composition.Minus thermal sensitivity coating composition: heat affected zone can form crosslink bond (cross linkage), and structural strength is increased, thus can not be dissolved in developer solution, but irradiated region then can not dissolve.
Image area in the offset print technology and non-image district are after exposure process makes said version be exposed to light source (this light source is made up of near-infrared radiation (NIR)) and form.Near-infrared radiation preferably can directly change into heat, or converts heat with a kind of composition of composition to via chemical reaction.If use the positive type light sensitive version, be not light area (area) corresponding to the image area on the said version, but then allow light to see through to the positive-working, thermally sensitive based coating composition corresponding to non-image district, it is become more be prone to dissolve and remove.If use the negative photosensitive version then situation and above-mentioned opposite.
U.S. Pat 6063544, US5372907, US 5340699; US 5372915, and US 5466577, and US 5491046 and US 5663037 disclose the method for relevant hectographic printing; After the common problem that only said patent faced is the video picture of individual layer galley; Its image area that manifests often has image retention (smudging), can't under long-time, effective printing be provided, so that the image definition and the printing quality inequality of printing generation.
U.S. Pat 6352811, US 6358669, US 6440633, US 6534238, US 6537735, US 6555291, US 6649324 and US 7582407 propose improving technology to US 6280899.
With US 6440633 is example; Mention in the said literary composition that the prior art multilayer system is in order to improve original composition (lipophilicity) and the not good problem of substrate (water wettability) adhesion; But still exist many problems in the multilayer system; For example: the generation of the residual dirt in back (smudging) of developing, however also there is identical problem in individual layer galley.Therefore, how improving problem that known individual layer galley faced effectively is the developing direction of outbalance comparatively speaking.
Taiwan patent TW 583508, TW 200617591 and TW 584787 disclose and attempt improving the sharpness of printed images and the content of printing quality; Its characteristics are to add crosslinking chemical and thermochemistry acid/light acid producing agent (photoacid generators), improve original development and the homogenieity that divests.Said technology is added crosslinking chemical and thermochemistry acid to heat-sensitive composition, and thermochemistry acid possibly make the storage characteristics variation of composition, and the thermochemistry acid that before uncoated, under the condition of UV radiation, is present in specifically in the composition is prone to take place qualitative change.Therefore, need extra interpolation acid stabilizing agent as stable component in the known compositions.But, in heat-sensitive composition, add crosslinking chemical and thermochemistry acid, can not improve the solvent resistance of original composition.
Offset printing technology is according to oil and the immiscible characteristic of water; Wherein oily matter or printing ink (ink) by sorption in image area (image area); But not image area tool water wettability, fountain solution then by sorption in non-image district, said fountain solution can prevent that printing ink is adhered to non-image area.When the surface of suitable allotment applied printing ink, non-image district repelled printing ink, and image area is accepted printing ink simultaneously, and the ink transfer in the subsequent picture district is to planning the material surface of duplicating image, promptly like surfaces such as paper, clothes.But; Owing to contain solvent in the fountain solution; Can slowly corrode image area, shorten the serviceable life of galley, therefore; How to let heat-sensitive composition that fountain solution is had the important topic that solvent resistance becomes offset printing technology, but seldom discuss how to improve the solvent resistance of composition in the prior art fountain solution.
