Definitions
- This invention relates to an electrosensitive recording blanks for recording characters, graphic patterns or the like in a visible form through electric signal.
- electrosensitive recording blanks comprise a base sheet of paper, plastic film or the like, a colored electroconductive layer coated on a surface of said base sheet and a white marking layer of low electrical resistance covered on said colored electro-conductive layer.
- the colored electro-conductive layer is formed by coating on the base sheet with a coating composition consisting of a mixture of deep colored electro-conductive carbon black with a binder and in some cases further depositing vaporized metal on the thus formed coating layer in order "United States Patent 0 to obtain a good contrast of the recorded image and to ice white marking layer being partially broken to expose the inner dark or black conductive coating layer.
- the principal object of the invention is to provide an improved recording blank capable of recording at a low voltage, in which the outer white has a reduced electrical resistance so that the difference in the electro-conductivity between the under layer and the white marking layer may be reduced.
- Another object is to provide a recording blank which scarcely involves production of odors and dusts during recording operation.
- a further object is to provide a recording blank capable of obtaining high-contrast, sharp images.
- the electro-sensitive recording blank according to the invention comprises a backing layer of paper, a darkand wherein R is hydrogen or alkyl having 1-4 carbon atoms, each of R R and R is alkyl, at least one of R R and R is alkyl having at least 10 carbon atoms and X is anionic radical. All of R R and R may be alkyl having at least 10 carbon atoms, but the remaining one or two of R R and R may be lower alkyl.
- alkyl groups with more than 10 carbon atoms there may be included lauryl, myristyl, palmityl and stearyl and among lower alkyl, groups there may be included methyl, ethyl and n-propyl.
- X a quaternary ammonium salt, any of halogen ions (Cl-, Br-, and I) and alkyl sulfate anion (CI-12504,) may be used.
- the polymers used in this invention may be copolymers of the above-mentioned monomers with the other monomers such as aromatic vinyls, vinyl esters and vinyl ethers.
- the white marking layer is hardly accompanied by odor development during the process of decomposing at a recording stage.
- these polymers can be solubilized in organic solvents such as alcohol and ketones. Since the polymers utilized in this invention are of low electrical resistance, the resultant product requires a reduced power consumption and is active at a reduced threshold voltage.
- the above-mentioned polymers can be handled in the condition of aqueous base or solvent base.
- a coating color composition containing any of these polymers, a white pigment such conventional zinc oxide and titanium dioxide and a natural or synthetic binder can be applied to a base sheet having a colored conductive layer to form white marking layer by means of conventional coater.
- the content ratio of polymers in the coating color composition is not specifically limited but is preferably within the range of 1 to 30 weight percent of the total weight of the white pigment and the binder resin when desired decrease of electrical resistivity and opacity of white marking layer are taken into consideration.
- the degree of molecular weight of the polymers is not specifically restrictedso long as it has a viscosity which enables practical handling, but it may preferably be within the range of about 1,000 to 100,000.
- the base sheet may be selected from cellulose matrix sheet, plastic film sheet or synthetic paper, and colored conductive layer may be composed of well-known conductive carbon black, and aluminum foil or aluminized layer can also be utilized.
- Example 1 A paper web comprising 50 parts of bleached hardwood kraft pulp, 50 parts of bleached softwood kraft pulp, 0.5 parts of rosin and 2.5 parts of alum, and weighing 60 grams per square meter was prepared.
- the paper web was coated with a coating composition containing 45 parts of conductive carbon black, 115 parts of alkyl resin modified by styrene and 145 parts of toluol. Coated weight was grams per square meter on dry basis.
- the degree of electrical resistance of the resultant conductive coated paper sheet was 150 ohms per square.
- the mean molecular weight of the copolymer was about 8,000.
- the copolymer is referred to as Copolymer A in the Table 1.
- the Table 2 shows the power consumption of each sample required for reaching the reflection density of 1.0 scanned with 6 lines per millimeter.
- EXAMPLE 3 This example was similar to Example 1 except that the polymer obtained by polymerizing a monomer having the following chemical structure was used instead of Copolymer A of Example 1. The mean molecular weight of this polymer was about 8,000.
- EXAMPLE 4 This example was similar to Example 1 except that the polymer obtained by polymerizing a monomer having the following chemical structure was used instead of Copolymer A of Example 1. The mean molecular weight of this polymer was about 20,000.
- Example 5 This example was similar to Example 1 except that the polymer obtained by polymerizing a monomer having the following chemical structure was used instead of Copolymer A of Example 1. The mean molecular Weight of this polymer was about 5,000.
- An electro-sensitive recording blank comprising a backing layer having an electro-conductive dark-colored coating thereon and having on said electro-conductive dark-colored coating a white surface coating, said white surface coating essentially consisting of a White pigment, a binder and at least one polymer, said polymer essentially consisting of at least one monomer unit selected from the group consisting of the monomer units represented by the following structural formulas:
- R is hydrogen or alkyl having 1-4 carbon atoms, each of R R and R is alkyl and at least one of R R and R is alkyl having at least 10 carbon atoms, and X is anionic radical.
