Verfahren zur Herstellung von mit UV-Strahlung härtbaren Hartüberzugszusammensetzungen
摘要
<p>A method of making a UV curable hardcoat composition uses a strip-free process and produces hardcoats having good scribed tape-pull adhesion, high resistance to scratching and a low delta taber haze after abrading for 500 cycles with a 500 gram weight. UV curable hardcoat compositions are also provided which contain high solids contents and high mole percentages of photoinitiator. Compositions containing methoxypropanol as a water miscible alcohol and methylbenzoylformate as a photoinitiator exhibit high taber hardness and can be made by processes which obviate the need for a time and energy consuming solvent-strip step. The processes are not only shorter, but safer than processes which include a solvent-strip step.</p>
