Near-infrared absorbent adhesive composition and optical film

The present invention provides a good heat resistance, good optical characteristics, and can be a simple process for producing a near infrared-absorbing adhesive composition and an optical film optical filter. Near infrared absorbing dye containing and silicon-based adhesive, characterized by the near infrared absorbing pressure-sensitive adhesive composition, and an optical film comprising the near infrared ray absorbing layer formed by the near infrared absorbing adhesive composition.
