Technical field
The present invention relates to novel urea-urea hydride compounds.The invention still further relates to novel color former by using this urea-urea hydride compounds to obtain, and the recording materials by using this color former to obtain.
Color former of the present invention can be as the color former of the recording materials that use record energy such as heat, pressure, the invention particularly relates to the color former of the stability in storage that can give coloured part (source recording material surface) not and colour developing image improvement, and recording materials, especially thermal recording medium by using this color former to obtain.
Background technology
It is known using the various chemistry of records energy such as heat, the pressure system of adding lustre to.In the middle of these systems, very early with regard to known by usually by the two-pack system of adding lustre to that system forms of adding lustre to, this two-pack system of adding lustre to is made up of with the developer that can cause colour developing when contacting with dyestuff former colourless or light dyestuff former, and this system of adding lustre to is generally used for recording materials.For example, the pressure sensitive recording material of applying pressure record uses heat thermal recording medium that writes down and the photosensitive recording material that uses optical recording.
The pressure sensitive recording material uses with plane form usually, with stationery seemingly.Usually,, the gained emulsifying soln is become several microns, again emulsion is shaped to microcapsule and obtains the pressure sensitive recording material by dyestuff former being dissolved in the suitable solvent.To make microcapsule coating surface and developer coating surface toward each other by being stacked together up and down with the first layer paper (also being referred to as paper here) of microcapsule coated substrate acquisition with by the second layer paper (also being referred to as down paper here) that is coated with another base material acquisition with the developer layer that contains developer.When by writing, knock or similar fashion when bringing pressure to bear on the gained assembly, microcapsule are destroyed, discharge the content that comprises dyestuff former.Dyestuff former is transferred on the developer layer, contacts with developer, makes color reaction takes place, and has obtained visual record.
In recent years, comprise with the usually employing in various machine information devices such as facsimile recorder, printer, register etc. of the thermal photography method of heat energy record.The thermal recording medium that is used for the thermal photography method has the characteristic such as the high whiteness of many excellences, is similar to the outward appearance and the feel of common plane paper, and the excellent properties that is used to write down, for example, and high developing sensitivity.The thermal photography method is an ideal, and for example the device that uses in the method is little, does not need to safeguard and do not produce noise.Therefore, the use range of thermal photography method obtains increasing in multiple field, terminal, the label of the register that for example is used to measure, facsimile recorder, printer, computer and be used for the ticket vendor field of railway tickets etc.
In the thermal photography method, the main use by on base material, forming the recording materials of the layer acquisition that add lustre to that contains the two-pack color former, and the component of heat-sensitive composition is by being in contact with one another with the thermal treatment recording materials, this hotwork can be supplied with by thermal head (thermal head), brand, laser beam or analogue for record, thereby develops the color and record.Many compositions as color former are those compositions colourless or light by using, that obtain for electron stain precursor (especially leuco dye) and acid developer such as phenolic compound.By the example that uses the recording materials that dyestuff former obtains be by use crystal violet lactone and 4,4 '-temperature-sensitive paper (consulting U.S. patent 3539375 etc.) that the binding substances of isopropylidene diphenol (dihydroxyphenyl propane) obtains as the temperature-sensitive color former.
As dyestuff former that is used for above-mentioned each recording method and developer, main respectively the use given electron compound and is subjected to electron compound.This is because give electron compound and be subjected to electron compound for example to have the characteristic of following excellence: contacting with each other as the dyestuff former of giving electron compound with as the developer that is subjected to electron compound has obtained to have the image of highdensity almost instantaneous colour developing; Can obtain near the outward appearance of white and can obtain various tones as red, orange, yellow, green, blue, black etc.Yet the chemical-resistant of the colour developing image that is obtained is inferior, thus with plastic plate or rubber in the softening agent that contains, or during the chemical that contains in food or makeup contact, record content easily dissolved.Also have, the record stability in storage of colour developing image is so poor, and when making the time of lacking relatively under being exposed to sunlight, the record content is faded, and perhaps worse, the record content disappears.Therefore, comprise that the color former of dyestuff former and developer obviously is restricted on their purposes, and urgent hope makes improvements.
In recent years, be that the phenolic compound of representative is considered to be unsuitable for use with the dihydroxyphenyl propane, because they are likely the internal secretion interfering factors, therefore non-phenolic developer is preferred.
In order to satisfy this requirement, for example, JP-A-59-115887 and U.S. patent 4521793 disclose the recording materials of the binding substances that comprises the color former that contains aromatic isocyanate compound and imino-compound, as the recording materials with high shelf stability.These reference disclose various recording materials, wherein can two kinds of color formers be in contact with one another to react as heat, pressure, light or analogue by applying record.These reference have been described by suitable selection color former can generate shades of colour as red, orange, yellow, light brown, dun etc.Yet in the invention disclosed, the colour developing of black remains inadequate in these reference, and black be in the situation of present normally used recording materials press for.
JP-A-8-2111 and JP-A-8-2112 disclose the thermal recording medium with the layer that adds lustre to that contains colourless or light dyestuff former and carbamide compound, as the thermal recording medium by using non-phenolic developer to obtain.Yet the colorant density of these recording materials is low and have an inadequate shelf stability.
JP-A-5-116459 disclose have the temperature-sensitive that contains colourless or light dyestuff former and solsonylurea compounds add lustre to the layer thermal recording medium.Yet the whiteness of these recording materials is low and have an inadequate shelf stability.
