Description
Technical field
The present invention relates to a kind of photographic material, particularly a kind of two sides is with the plastic-coated paper-based of antistatic bottom.
Background technology
Traditional single face light sensation colour photographic paper can only simultaneously expose at printing paper, during its exposure, light reaches on the paper substrate through behind the emulsion layer, and wherein a part of light sees through paper substrate, another part light is reflected back again emulsion layer, thereby improved the photosensitive property of product, can only form the single face image, reverse side does not have image, can only be contained in like this photo frame or photograph album the inside single face appreciates, virtually limit the usable range of printing paper as image-carrier, reduced the utilization factor of printing paper, increased manufacturing cost.
For the utilization factor of printing paper is provided, satisfy consumers in general at the individual demand of the aspects such as business card, personalized desk calendar, menu, auction room's sample volume, hotel sample board, invitation card, work card, trade promotion promotional pamphlet, occurred the double-face light sensation colour photographic paper product on the market.
The paper substrate of traditional single face light sensation colour photographic paper comprises asbestos base paper and is coated on polymeric layer and the contact layer of asbestos base paper one side that contact layer is used for improving the viscosity fastness of asbestos base paper and sensitive emulsion layer; Another side at asbestos base paper is coated with polymeric layer and antistatic backing, and antistatic backing is used for bonding surface imaging material and does not produce the static that causes photosensitive property and be coated with apparent deterioration in coating is produced.
For realizing double-face imaging, require double-face light sensation colour photographic paper paper substrate the two sides all scribble emulsion, in order all to coat photosensitive emulsion on the two sides of paper substrate, need to be at the two sides of asbestos base paper difference coated polymeric layer and contact layer, the needs of producing to satisfy double-face light sensation colour photographic paper.There are the following problems when being used for double-face light sensation colour photographic paper production for such paper substrate: two contact layers of (1) paper substrate all are the coatings that contains the water absorptivity materials such as gelatin, in actual production process, because the adhesion meeting between the paper substrate causes the part of paper substrate and produces static, cause great waste to production; In addition, because long-term between two contact layers directly contact, paper substrate causes product rejection depositing, adhesion occurring easily in the transportation and under the environment of high humidity.(2) if on the surface of contact layer antistatic backing is set separately then causes easily the surface resistance of paper substrate to increase, make the dust in the easy absorbed air of paper substrate cause the apparent disadvantages such as the dirty point of apparent appearance, simultaneously static increase also can cause the apparent of paper substrate to grow dim, also may cause the deterioration of photographic property when serious and produce the static spot, cause product rejection.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of two sides with the plastic-coated paper-based of antistatic bottom.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of two sides is with the plastic-coated paper-based of antistatic bottom, it comprises asbestos base paper and is arranged on the two-sided polymeric layer of asbestos base paper, be provided with antistatic bottom on the described polymeric layer, antistatic agent in the antistatic bottom and the weight ratio of antiblocking agent are 1:10~10:1, and the surface resistance of described plastic-coated paper-based is 10
6~ 10
10Ω.
The weight ratio of antistatic agent and antiblocking agent is 1:5~5:1 in the described antistatic bottom.
