のである。(Problems to be solved by conventional techniques and inventions) In recent years,
The spread of LV, CD, WO, and FD is remarkable, but these optical information recording media that record and/or reproduce information using a light beam generally have a transparent plastic protection on the information recording surface. There is a layer, and a laser beam focused through a lens is irradiated from above this protective layer to carve a minute pattern of several microns to submicrons to record the forward tilt or reflect information that has already been recorded. It can be reproduced by reading changes in light.

た。This optical obstacle is caused by three types of servo mechanisms (a focus servo that controls the height, a focus servo that controls the height, and a (tracking servo to control the position in the perpendicular direction, jitter servo to control the speed of the laser), and the size of the obstacle exceeds the control capability of the laser, making accurate recording and playback impossible. A problem arose.

The objective is to obtain an ink that forms a coating film with a visible density that allows accurate recording and reproduction.

、即ち１本発明は、着色剤と、樹脂と。(Means for solving the problem) As a result of research on the above problem, the present inventors found that
The main reason for this is that the ink coating film transmits the laser light used to write or read signals on the optical information recording medium (80 nm, which is close to the oscillation wavelength of the currently commonly used gallium-arsenide semiconductor laser light). The present invention was completed based on the knowledge that the purpose of the present invention is to attenuate the colorant and the resin.

を有するものである。That is, 1. Even if the ink for optical information recording media according to the present invention forms a coating film on the signal recording surface of the optical information recording medium, optical disturbances caused by the coating film can be caused by laser irradiation! This is within the control capability of the device's servo mechanism, and accurate recording and playback can be performed.As mentioned above, it can be used to increase added value with signatures such as Archis 1~, and to sort content. It has the usefulness of improving work efficiency by marking it.
尚、本インキは、筆記具に用いるのみならず。Furthermore, this ink is not only used for writing instruments.

様な考え方で同様な効果が奏しえること勿論である。By adjusting the physical properties using conventionally known additives,
It can also be used for printing, stamping, etc., and furthermore,
In the present invention, a gallium-arsenic semiconductor, which is currently used for boat fishing, is used as a laser light source, but He
It goes without saying that the same effect can be achieved with other laser beams, such as a -Ne gas laser, using the same concept.
