A phenolic compound of a phenyl sulfonyl or diphenyl sulfone structure is used as the thermal sensitive color development agent. Deep exploratory researches discover that the phenolic compound of the phenyl sulfonyl or diphenyl sulfone structure general formula has excellent function of preventing the mechanical pulp/ chemical mechanical pulp thermal paper from fading; and by using the phenolic compound of the phenyl sulfonyl or diphenyl sulfone structure general formula as the color development agent of a thermal sensitive recording layer, the purpose of preventing the thermal paper from fading can be fulfilled.
Description
Technical field
The invention belongs to the heat-sensitive paper technical field, relate in particular to a kind of manufacturing approach that can prevent to contain the heat-sensitive paper that machine slurry/change machine slurry heat-sensitive paper fades.
Background technology
Heat-sensitive paper has obtained significant progress and application widely since the nineteen seventies industrialization, its field has covered commercial paper, office automation, communication fax, Medical Instruments, label and lottery ticket etc.
The basic comprising of heat-sensitive paper is on basic paper, to scribble precoated shet and heat sensitive recording layer, and some high-end kind also must be pushed up and is coated with.Its chromophoric mechanism is, is acidic materials (developer) and the leuco dye with lactonic ring structure as electronq donor as the phenol of electron acceptor, and under the effect of heat, developer is captured electronics from recessive dyestuff, makes its lactonic ring cracking and color development.
In recent years, the heat-sensitive paper market competition is very violent.Particularly low and middle-grade kinds; The shared cost proportion of body paper is quite big; And contain machine slurry/change machine slurry, and the waste paper etc. that comprises thermomechanical pulp (TMP), chemical heat grinding machine slurry (CTMP), pressure defibrator slurry (PTMP), disc mill slurry (RMP), SGW (SGW) and contain said slurry kind, price is relatively cheap; With the characteristic of high bulk, industry is generally all used to join and is copied production temperature-sensitive body paper.In the heat-sensitive layer formulation for coating material, be the leuco dye except that using fluorane, generally use diphenylol benzene alkane (BPA) as developer.The heat-sensitive paper that adopts this technology to process, under normal temperature environment, image faded rapidly in 1-2 month after sensible heat is printed, and along with the increase of machine slurry/change machine slurry proportioning or the raising of envionmental humidity, had more quickened the process of bleach effect.As everyone knows, join the various machine slurry/change machine slurries of copying body paper, belong to the high yield pulp category that contains a large amount of lignins.In pulping process, the chemicals consumption is few, mainly leans on heating power and pressure defibre, thereby in pulping process, has kept at high proportion in the lignin, has also left over other materials of major part and group in the wood structure.Lignin is the phenolic compounds that gathers that is formed a tridimensional network that contains various sophisticated functions groups by the mutual polymerization in phenylpropyl alcohol alkyl structure unit; For the heat-sensitive paper of color development; The three-dimensional structure of this complicacy that exists in the machine slurry/chemical pulp and multiple functional group; Even under the normal temperature state,, be easy to receive in the machine slurry these the huge and impacts sophisticated functions group for the molecular structure as developer BPA; Cause the electric function that receives of BPA to fall weak gradually, thereby cause the lactonic ring of dyestuff closed heavily again so that disappear.On the other hand, these the complicated functional groups during also not eliminating machine is starched produce negative effect to the lactonic ring that splits in the dyestuff.The result of all these effects has finally caused fading of heat sensitive image, along with the rising of environment temperature and the increase of relative humidity, has further quickened this process.The electrothermal sensitive recording paper that how to prevent to contain organic slurry/change machine slurry fades, and prolongs its service life and has caused industry and pay attention to widely.
Summary of the invention
It is the manufacturing approach of the heat-sensitive paper of temperature-sensitive developer that technical problem to be solved by this invention provides a kind of phenolic group compound with benzene sulfonyl class or diphenyl sulphone (DPS) class formation general formula, thereby impedance machine slurry/change machine slurry is for the generation of heat-sensitive paper bleach effect.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of manufacturing approach that can prevent to contain the heat-sensitive paper that machine slurry/change machine slurry heat-sensitive paper fades, the phenolic group compound of application benzene sulfonyl class or diphenyl sulphone (DPS) class formation is as the temperature-sensitive developer.
The general structure of the phenolic group compound developer of said benzene sulfonyl class is:
In the formula, X=H or low alkyl group, R
1, R
2, R
3=H, halogen atom, low alkyl group or cycloalkyl;
The general structure of the phenolic group compound developer of diphenyl sulphone (DPS) class is:
In the formula, R
1=H, alkyl, cycloalkyl, R
2, R
3=C
2-C
4Thiazolinyl, alkyl, aryl.
The said machine slurry/change machine slurry that contains is meant one or more that contain part or all of following high yield pulp: thermomechanical pulp, chemical heat grinding machine slurry, pressure defibrator slurry, disc mill are starched, SGW, or contain the pulp from decoloured waste paper of above-mentioned one or more slurries.
The present invention is through deep exploratory development; Find that the phenolic group compound of benzene sulfonyl class or diphenyl sulphone (DPS) class formation general formula has the function of very good impedance machine slurry/change machine slurry heat-sensitive paper bleach effect; Adopt the phenolic group compound of benzene sulfonyl class or diphenyl sulphone (DPS) class formation general formula to use, can reach the purpose that prevents that heat-sensitive paper from fading as the developer of heat sensitive recording layer.Because the phenolic group compound of benzene sulfonyl class or diphenyl sulphone (DPS) class formation general formula possibly have good space steric effect as the functional group of the bulky complex that developer is starched machine slurry/change machine; Make it receive electric function to obtain protection; Suppressed some group in machine slurry/change machine slurry receives electric function to developer impact; Simultaneously also might give some protection to the lactonic ring of having opened already in the dye structure; The bleach effect that has consequently suppressed image, thereby the useful life that has prolonged heat-sensitive paper widely.
