• the content of reactive silica particles in component (A) is the value in the solid content of component (A).
• Example 1 In the case of high contrast tie strength, external haze appears and is prevented by adding an agent to the PMMA fine particles, even if the hard coat layer has a large film thickness compared to the vertical particle diameter of 5 m.
• the ratio is 1, no dispersing agent is added, so that the surface unevenness is hardly formed and the external haze value becomes small, and the antiglare property is obtained.
• Comparative Example 2 where the wrinkles of the hard coat layer were the same as the vertical diameter of the particles in order to form the surface irregularities, the surface where the irregularities were not present appeared and the surface was uneven in anti-glare properties.
• Comparative Example 3 Comparative Example 3
• the external haze value becomes very large and the condition called “Shirocha-ke” has been reached.
• the external haze value varies depending on the amount of dispersant added, but it can be seen that the internal haze value has hardly changed.
• male examples 6 to 8 in Lan Thailand, it can be seen that the external haze value can be made higher than in comparative example 5 even if the wrinkle of the dispersant is changed.
• Comparative Example 4 does not contain silica-based fine particles, a sufficient external haze value cannot be obtained.
• Comparative Example 6 is an example in which the particles were not used and the agent was added in the system, but the external haze was hardly exhibited, and the antiglare property was not exhibited.
• the antiglare property can be controlled without affecting the contrast.
• the antiglare hard coat film of the present invention is an antiglare hard coat film provided with a hard coat layer S containing particles, and has an external haze. Controls specular light to a desired value without lowering the contrast, and is suitable for attaching P-dimension l ⁇ fg ⁇ f (4tg etc.) to displays such as CRT, LCD, PDP, etc. It is particularly suitable for use in LCDs and the like.
